Error popups - they appear at one place, I have moved them so all are visible

SUMMARY

I am a part of shared Google calendar, and I added that calendar to KOrganizer.
Three times so far, I saw a bunch of popups, saying "Error while trying to
delete calendar item. Error was: No items found". I was not using Korganizer at
that time, it was running in the background. I have Korganizer connected to the
calendar widget in my panel, but I did not open that widget today. The deleting
happened last october, then on 2020-03-24, and again today (2020-04-06).

When checking the calendar bin through the webpage, I see that KOrganizer
successfully deleted some of the events. The events are only from said shared
calendar - none of my individual events are affected. Also, the deleted events
have nothing in common. They are in the future, in the past, they may or may
not belong to the same "recurring event" group, I may be going, I may not be
going, I may not be invited. In October, about 30 events were affected, last
month it was a little less.

When it happened for the second time, I asked to have my write access to the
calendar revoked. This was a good step, because today, no events were actually
removed - I only see the popups as usual, and permission issues in the log.

STEPS TO REPRODUCE
1. I have no idea how to reproduce this, I am terribly sorry. A colleague said
today she was changing something in the calendar before KOrganizer went crazy.
I have no idea if someone was interacting with the calendar in the two previous
cases. 

OBSERVED RESULT

When working on the computer (korganizer is not even open), suddenly popups
appear, saying that events could not be deleted (I didn't ask for any deletes).
In the google calendar bin online, I can see the affected events (or nothing,
if my write access was revoked), and I can restore the items manually.

EXPECTED RESULT

There are other poeple's events being deleted in the background, by my
computer, without my permission. I don't want to have events deleted without my
explicit request for it. 

SOFTWARE/OS VERSIONS
Windows: 
macOS: 
Linux/KDE Plasma: 5.5.13-1-MANJARO
KDE Plasma Version: 5.18.3
KDE Frameworks Version: 5.68.0
Qt Version: 5.14.1

ADDITIONAL INFORMATION

When writing this report, I noticed that the dates of the issue (October,
03-24) match the switch in daylight saving time - so it could be caused by time
issues? Today morning, I restarted from windows, and this moves my system
clock, so I had to move the system time oen hour backward after that.

Since only one attachment can be added, this is the journalctl from today
(changed event names to something more descriptive)
