When I remove a video from a playlist the counter that shows the number of items in the playlist does not decrease. For example the text on the left side of playlist says: "Your Video Playlist (8)", I remove an item, the item gets removed but the counter remains at 8.

On a similar note I would like to say that the guys that are developing this webpage are really good. The whole user experience is really amazing - both the functionality and design are top notch. And I know a bit about those things since I teach web technologies at a university.
