It was working fine, but now all of a sudden any event I create on my iPhone 5 don't sync via iCloud to my Macbook Pro. I can however delete events on my iPhone and they will be removed from my Macbook Pro. Events I create on my Macbook Pro show up on the calendar on my iPhone. I also have duplicate events on my iPhone but not on my Macbook Pro. I'm very confused with this issue! iTunes is set to Backup to iCloud and all my preferences seem correct.
