I use Google Calendar and generally synchronisation with Korganiser works reasonably. If I enter a multi day event into Google Calendar it synchronises with Korganiser. If I enter a multi day event into Korganiser it does not synchronise with Google Calendar.

Is there some configuration I have missed? I can't find it as a known issue.

I use openSUSE 15.0 and use the KDE products that that distribution contains.
Korganiser 5.7.3
