Unable to remove duplicate birthdays on iCloud.com
I recently turned on the "Show Birthdays calendar" option in the calendar preferences on iCloud.com. As the birthdays started to populate the calendar I was dismayed to noticed that all the birthdays were duplicated multiple (5-6) times on each day. I assumed that this was because I have deleted and re-imported my contacts from a vCard file a number of times and thought that by deleting all my contacts it may have resolved the problem. No such luck. I now have 0 contacts saved on iCloud, but still have multiple birthdays entries. Any advice here would be very much appreciated. Thanks in advance.
