Trying to put headers in a document and Word doesn't seem to have the old indicators for reverting back to 1 or continuing the preceding numbers. How can you fix documents without that? Screws things up royally. Doesn't work in MacOS Word or Google Docx

Hi, @Claudia Rollistin

The reason the "restart at 1 / continue numbering" buttons feel like they've gone missing is that on Mac, Word hides most of this behind the right-click menu, and the Windows-only "Set Numbering Value" command simply doesn't exist in the Mac version. So you're not imagining it.

A few things worth trying that go a bit further than restarting:

If a heading has jumped back to 1 but should keep going, right-click directly on the number itself (not the text) and pick Continue Numbering. On Mac that option only shows up when you click the number, which is easy to miss.

If you need a very specific number that the right-click menu won't give you, select just that heading, right-click, choose Bullets and Numbering, go to the Outline Numbered tab, click Customize, change the start number, and make sure "Apply changes to: Selected text" is set, otherwise it renumbers the whole document.

If numbers keep misbehaving no matter what you do, the problem is usually that your headings belong to several separate lists instead of one. Click in your first Heading 1, go to Home, click the Multilevel List button, then Define New Multilevel List, click More, and for each level set "Link level to style" to Heading 1, Heading 2, and so on. After that, you never touch the numbering buttons again; you just apply the heading style and the number follows automatically.

One more thing: a file that has been through Google Docs and back often carries broken list definitions that can't be repaired. The cleanest fix is to paste the text into a fresh Word document as unformatted text and reapply the heading styles there. It's a bit of work, but it is recommended as the one approach that reliably clears this kind of corruption.

Hope that gets your document back under control.

    Rebuild the heading sequence in the Word for Mac desktop app by applying the built-in Heading 1, Heading 2, … styles and then attaching one multilevel list to those headings.

    Repair the heading numbering

    1. Save a backup copy of the document before changing its list structure.
    2. Select every top-level heading and apply Home → Styles → Heading 1.
    3. Apply Heading 2 to second-level headings, Heading 3 to third-level headings, and so forth. Do not skip levels.
    4. Select the first Heading 1 paragraph.
    5. Go to Home → Paragraph → Multilevel List.
    6. Under List Library, select a template whose preview includes Heading 1, Heading 2, and similar labels.

    The expected result is one connected outline: 1, 1.1, 1.2, 2, 2.1, rather than independent numbered lists. Microsoft specifically recommends built-in heading styles with a multilevel-list template for numbered headings.^1^ On macOS, heading styles are selected from Home → Styles.^2^

    Avoid typing or replacing heading numbers manually. Word then loses the relationship between the displayed number and its list sequence, which can produce more numbering errors after editing.^3^

    Correct one broken sequence without rebuilding everything

    If the headings already belong to the same numbered structure and only one number is wrong:

    To restart at 1

    1. Select the heading that should begin the new sequence.
    2. Control-click or right-click it.
    3. Select Restart numbering.

    That is the documented Mac command for starting a numbered sequence over.^4^

    To set a specific starting number

    1. Click in the affected numbered heading.
    2. Open Home → Paragraph → Numbering ▼ → Define New Number Format.
    3. Enter the required value in Start at.
    4. Select OK.

    Word for Mac documents that path for changing a list’s starting number.^5^

    Use these local corrections only when the rest of the outline is sound. If several headings are wrong, rebuilding with built-in heading styles and one multilevel list is more reliable than correcting each displayed number.

    If the numbering changes or disappears again

    • Perform the repair in the Word desktop app for Mac, not Google Docs. Editing a .docx through another editor can alter Word’s list definitions; a Microsoft Q&A moderator recommends desktop Word for stable multilevel numbering.^6^
    • If Track Changes is enabled, accept the outstanding revisions and turn tracking off before judging the resulting numbering; tracked revisions can prevent the expected numbering from appearing.^6^
    • Do not merely format ordinary paragraphs to look like headings. Built-in Heading styles carry the structural level that the numbering scheme uses.

    I have no idea what others are referring to. The AI reply is interjecting totally irrelevant info re Paragraph Numbering & Numbered Lists as well as other misleading, confusing instruction. Everything you need can be found by going to Insert> Page Numbers - Format in the main menu bar.

    User's image

    Page Numbering normally starts at 1 & runs consecutively through the document . The exception is when there are Section Breaks & the option to Continue fro previous section is deselected

    FWIW, I suggest avoiding the built-in Headers & Footers provided in the program. Most of them appear to have been created by designers rather than users & have no real-world value. Create your own 🙂
