Here is what I did. Unsync all pics, albums, faces, events, etc from ipad, and when asked if you want to remove them say yes. After that sync is done, and all pics are removed from ipad, click again to sync pictures, but only sync faces, nothing else. After that sync, faces should all be there. Then select whatever else you want to sync, events, places, albums, and photos. Sync again. Voila, all is synced.
