How do you delete extra Confluence Team Calendar Jira Sprint events?

Question

I added that event type twice to my calendar by mistake with no apparent way to delete 1 of the 2 which show exactly the same information.

I encountered the same problem, but eventually figured it out. If you go to "Calendars" at the top (blue menu, just to the left of "Create") you can delete calendars and event types too (and give them different colours)
