A bug in my iPhone

I found a bug in my iPhone. Doesn’t bother me but drives my 20 month old daughter crazy…

I’ve seen this a couple of times, it seems to duplicate the ‘cover’ image for one video onto other videos. I haven’t seen a pattern in it yet. Doesn’t seem to matter if the video with the incorrect cover image has a cover image associated with it or not. Sometimes the cover images from TV shows or Podcasts are in the wrong place too. Most annoying for my daughter when she wants to watch WALL·E but clicks on The Last Lecture. She gets a bit upset after the third or fourth try.
