How do I remove duplicate Calendar entries

After logging out and back in of iCloud on my Mac Mini to take care of some glitches I find that *all* of my Calendar entries have been duplicated. That is all events I’ve entered, but not the automatic holidays, nor birthdays grabbed from Contacts.

How do I get rid of the duplicates without having to manually select and delete each one?

Also found that my signatures in Mail have disappeared, although that’s not a big deal, comparatively.

BTW, Calendar entries are not duplicated on my iPhone or iPad and Mail signatures are intact on both those devices.

Mac Mini late 2014, OS 11.2.3

Ahhh, so when I had it Show Calendar List, the two "blue-coded" (Home and Calendar) calendars were both checked. When I unchecked Home, the duplicate entries went away!
