I've got a problem with playlists on my new iPod Touch. When I create a playlist on the iPod and name it, it works fine until I sync the iPod. I have the iPod set to manual sync. When I connect the iPod to the computer, the new playlist does not show up in iTunes, and it gets erased from the iPod. I've tested this twice and the same thing has happened. Am I missing something, or is there some sort of software glitch?
