A registry reset should fix that. Go into the maintenance tools for 2020. For version ten the icon is a red toolbox. Delete your temp files. They never all disappear so just do it once 🙂
Then run Repair Com and then select 2020 design registry reset to reset your software. This will set the program back to its default values so any changes you have made to the quick access bar or sorting of the catalog list will need to be redone.
