Excel flipped down on Mac

Hi! My computer decided to flip upside down excel sheets once I installed Mac OS. Yeah, it creates all sorts of problems for me and restarting/reinstalling excel does not help. Any ideas?

This is a known issue, your Excel is out of date and needs to be updated to be compatible with Catalina (Latest)
Download and run the latest version of AutoUpdate to update your Office installation

Microsoft reference:

Hey there!
What if you scroll down the spreadsheet, then back up, it flips it right-side up again. However some formatting is missing, and the column headings don’t show for ever column. Huge problem.
