Calendar not shown

I want to show four Google calendars in my eM Client, but unfortunately only three of the four calendars are shown. In Gmail on web all four calendars are shown correctly.
I hope you can help.

how many calendars do you have in the left column? Login to the calendar in a browser and open its settings to see if the checkbox is ticked near the every single calendar you want to show in eM Client. If it is not, please tick it and let me know if it helped.


this did not solve the problem.

After having tried different things, the button “Aktualisieren” (Refresh?) made my day.

Best regards,
