Hi @Susan M. Smith ,
Did this problem only appear in Word? How about other Office products?
Did this problem appear in all Word documents?
Where did you save the documents?
You can try to create a new Word document in desktop and check the result.
I suggest you try to re-set the Word default template, go to C:\Users\user name\AppData\Roaming\Microsoft\Templates. Rename the Normal.dotm to Normal.dotm.old, then re-open Word.
If the issue still existed try to open it in safe mode running the following command: Press Win + R, type "winword/safe" in the blank box, press Enter. If it works fine in safe mode, please check the add-ins in your Word and disable them.
