How can I remove duplicate birthdays from iCloud?
My birthdays show up twice on icloud but I managed to remove the double entries from my iMac calendar, following some advice in the discussion board. I can't remove them from icloud though. Strangely, the only birthday that is not displayed twice in my icloud calendar does not exist at all as a birthday field in my contact, neither on icloud nor on my mac. Any ideas what to do?
iMac (27-inch, Late 2013), OS X Mavericks (10.9.1)
