Reply to Musc Importation in Traktor Dilemma

So I'm been reorganizing my music A LOT lately, and I'm coming to find that any time I decide to delete a song from my collection, Traktor does not update itself so as to accurately reflect what music I have in iTunes. However it does still add/import tracks every time I open it. But I have to manually go into Traktor and delete stuff that I already deleted off of iTunes.

In addition, when I edited my music, such as rating the song/adding stuff into the comments, Traktor adds a duplicate of the song to the collection. The thing is I can't even load the original song to the deck even if I wanted to, but somehow the file is still listed.

It's getting annoying having to manually edit/change all of this stuff every time I go into Traktor.

Is there some kind of setting I can turn on/off that can assist/fix all of this? I've looked around in the settings, but can't seem to find anything....

Thanks for the help
