Problem with the "save" function on Word.

I have been experiencing an issue with the “save” function of Word.

I have a MAC. Every time I open a Word document to read (without making any changes) Word requires me to save the document, even though I made no changes.

A microsoft support agent changed my user profile by uninstalling the license and reinstalling under a new user profile. Once that was done, I could create a new document, save it, and re-open it without Word requiring me to save the document.

The microsoft support agent advised me to create a new APPLE User profile because he believed the corrupt behavior in Word is linked to something inside my Mac OS user profile. I created a new profile but the problem still persists.

If I create a new document and paste data from an old document, save it, close it and re-open it, (without making any changes) Word requires me to save the document. Can this problem be fixed?
