my itunes keeps making copies of playlists when I add a song from my itouch?

[GabrielleLesnett]

whenever I add a song to a playlist from my iTouch my iTunes makes a duplicate of the playlist. for example I have a "workout" playlist and now i have "workout 1, 2, 3, 4" on my iTunes and iTouch. is there a way to just make it update the playlist and stop backing it up? thanks!!
