Playlist problem

I have a SAnsa Clip. The problem I have is that when I create 2 playlists on the player, it only remembers the last one I created. For ex: “Playlist One” might have pop songs and “Playlist 2” might have rock songs. When I finish creating “Playlist 2” songs, and when I detach it from the computer, the Clip only remembers all the songs from playlist 2 only on both the playlists. So I would have rock songs on both playlists and the pop songs from the playlist disappear.

Please help!!


A little more information?  There’s lots of ways to create playlists.  Could you describe the software or method you are using?
