iPod shuffle gen 3 won't sync playlist and song names.

Hi.

I recently synced all new songs to my ipod shuffle and while I'm able to sync and songs, the names won't sync. Which means when I press and hold the button it stays mute when it's supposed to be reading the song name, then for the playlists it just says "Playlist 1", "Playlist 2", etc.

On iTunes all the songs and playlist are appropriately named. I don't know what might be causing this.

Thanks!
