Playlist not recognized in sync manager

I am having an issue with new playlists not being recognized using iTunes in engine DJ. I make the adjustments add or delete songs from certain playlists make new playlists in iTunes first. Then go to engine DJ and resync or update iTunes in engine DJ. Once completed I hit sync manager and even though the playlist are there in the far left column, they are not in the sync manager. I even tried right clicking them to import playlist but it does not bring up any options. Anyone else having this problem or know a solid stable way to fix it? Please let me know. Please post in English by the way thanks

C est telment vrai Autant le son des denon est vraiment bon, autant tout le reste laisse vraiment à désirer
