Hello,
Sounds like you might be using Word in your web browser instead of the downloaded desktop app, since the web version is super limited with the table of contents settings and does not let you tweak the fonts or formatting easily.
Could you let me know if you are working from a web browser like Edge? Also when you say the numbering is wrong, do you mean the actual page numbers do not match the pages the headings are on, or do you mean the chapter numbers on the headings themselves are acting up?
Let me know so we can figure this out.
