Thanks for the logs!
Unfortunately, I don’t have any idea what the problem could be.
When I created the account, I had 3 calendars, in my kolab server. Since then I’ve created several new calendars. How do I add new calendars to my account?
Currently you either need to create an additional account adding only this resource or delete the one you have and add one account with all resources. We know this isn’t the optimal workflow and we’re already planning a release with the the first steps of a settings dialog. It should come in the not too distant future
