Hi Ben,
Based on what you shared, since the horizontal scroll bar returns after changing the page orientation, this may be a display or layout refresh issue. Please check the scroll bar setting by going to File > Options > Advanced > scroll to the Display section, and make sure Show horizontal scroll bar is selected. After that, select OK, then maximize and restore the Word window.
If there are any updates about the issue, please share them in the comments of this post. I'm happy to assist you further.
