I have an iMac and I have a problem with LibreOffice version 220.127.116.11. I did not have before I downloaded the latest version.
When I want to save the file, for example Section 5, and go “Save as” Section 5 to the desktop or other location, it saves the file as “TextEdit.app” I can not change the extension or don’t know how. It also assigns an extension looking like this: .sb-4597dc1d-ojSC9I. If I double click the file it opens in TextEdit but if I open LibreOffice and go “File; open, Desktop; Section5 it opens correctly but with the funny extension.
If I save to the desktop it shows a blank square with the right upper corner bent inside but not ODT or the green symbol for a spreadsheet.
I went through all the menus to see if I can find a strange setting but was unsuccessful.
