Dear Lincy45,
Good day! Thank you for posting to Microsoft Community. We are happy to help you
Please check whether your Office applications have been up to date with the latest version. You can reference this article:Update Office for Mac automatically - Office Support (microsoft.com).
If the problem persists, please try running Office by starting up your Mac in safe mode to see the result. This can help us check whether issues you are experiencing are caused by software that loads as your Mac starts up.

Another suggestion is to remove the Office folders to desktop:
- Completely quit all Office apps
- In Finder, press COMMAND +Shift+g.
- Enter ~/Library and click Go.
- Go to Containers folder, find the folder called Microsoft.Word
- Move this folder to your desktop by cut & paste.
- Relaunch Word for Mac application and see the results
If you still experience this situation, please inform us of the following information:
- The version information of Word you are using.
- Whether this phenomenon occurs in all documents?
Sincerely,
Tin | Microsoft Community Moderator
