duplicating playlists everytime i sync playlists to iphone

This only started happening after I downloaded the new itunes 12.2.1.16 (64bit). Every time i sync my playlists to my iphone and ipad, my playlists gets duplicated in itunes with 1 and 11 after the original playlist name. Is this happening to anyone else out there? Please let me know if you might have a solution to this. I backup my iphone and ipad to my pc.. not sure if that is messing it up too, but hopefully someone can help me out here. Thanks!
