Invitations will not go away

In the right column, under “Invitations” I have two invitations that I can not get rid of. Regardless of whether I click Accept, Maybe, or Decline or whether I send update or not. When I click one, it goes away for a minute then re-appears.

Hi, we know about this and it should be repaired in newest version… however it looks like some of the events can’t be dismissed at all, best solution so far seems to delete event and create it again.
