I have found an issue with the display of events in the calendar.
In the first picture you can see the event "Boot Düsseldorf" which ends the 26th January 2020
If is switch to year view no event is displayed (picture 2) at all and going back to the monthly view of January even "boot Düsseldorf" event vanishes (picture 3).
Is this a known "bug" or a problem on my single installation?
All the best!
