I have a macbook, a fedora 32 with plasma and an android phone. They are all signed into one google calendar. When I create an event on my mac, both android and KOrgnizer will receive it. However when I delete it on my mac, only android will sync and delete it while KOrganizer will leave it undeleted forever.

I see the same even if I move across machines which are all fedora 32/KDE. Perhaps related, when I "dismiss" a reminder for an event on one computer, I will still get the reminder when I logon to another machine. For completion, I mention that I can create events from any computer and they will appear on all other computers.

Info: Fedora 32, Kontact 5.13.2.
