Strange problem with Office 365 Word under Windows 11 home

    Several days ago while editing a Word 365 file under Windows 11 Home, my file split into 2 columns. I'd never seen this before. I went to layout and tried changing 2 columns back to 1. That did nothing.  

    Since then I have tried a number of things and nothing has worked. 

 At this point I have Word 365 files that are useable but they the text in them is tiny and hard to manipulate. I want my files to have normal sized characters.  

   I worked in IT for some 25 years so I know a good bit about this but this time I am stumped.

  Do any of you know how to fix this? Have you encountered anything like this?

 Your assistance is greatly appeciated. Thank you very much.
