I am running ios 8 on an ipad air 2. I added a folder containing 7 mp4 files to my itunes library. Then I synced those 7 files to my ipad and confirmed the videos were on my ipad. But then I decided I'd prefer to have them on a playlist so they are more organized, so I opened the Videos app on my ipad, tapped Edit, and manually deleted each one. Now, when I go to the Movies folder of my device in itunes, the 7 videos are still listed there even though they aren't on my ipad. Why would this happen? I've also tried syncing the playlist I created to my ipad, but nothing happens when I do. The playlist does not appear on my ipad when it's done. I don't know if it's because itunes thinks the videos are already on my ipad or what. Please help!
