Microsoft Excel - cannot delete user templates
Computer: Mac mini, MacOS 10.14.3
I have MS Office 2016 on my Mac. I can find my user-created templates in Library/Application Support/Microsoft/Office/User Templates/My Templates. If I drag one or more of them to the Trash, they disappear from the list of templates, but if I open the My Templates folder, their outlines and names are still there, and if I click on one, the template reappears. How can I get rid of them altogether?
