How Do I Move Word Files While Document Is Open?

Trying to move a powerpoint file or word file using the file -> move option on the upper bar. I am trying to move it from one folder to another on my mac.
*This is while I have the document open* When I try to click file->move, it immediately goes to “Microsoft Sharepoint” instead of asking me which file I want to move the document to.
Weirdly enough this problem only occurs when I am trying to move a ppt or word doc. I don’t have this problem for PDFs.
(P.S. I know that I can drag and drop and do all the other ways, I just am wondering why this way doesn’t work).
Would appreciate the help. Thank you!
