Google calendar sync error s- how to get rid of them

Google calendar sync errors

I am getting these errors every time em is syncing e-mails.
Unfortunately I don’t find a setting where I can delete those calendars to stop the problem.

What am I missing?

Any help is greatly appreciated.

Cheers

You can delete Internet Calendars by right-click on the calendar and choosing delete.

A better way to add Google Calendars is through Menu > Tools > Accounts, and adding a Google Calendar.
