Calendar invitations don't go to calendar

When a calendar invitation is sent to my icloud mail adress, which is also my apple-id, the invitation comes as mail only, despite my setting that it should come as a calendar notification.

Invitations to my other mail accounts show up in the calendar app as expected.

This is a nuisance. Any ideas how to male it so that invites to the icloud mail show up where they are supposed to?
