Need Help with Traktor Pro 2 and iTunes Library

My iTunes library won't update in Traktor Pro 2. I have to manually export my iTunes library every time and replace it again in my iTunes folder in order for it to "update". However, I have to do this EVERY time I make a small change in iTunes or else the change won't show in Traktor. How do I fix this? I have a mac...

I reinstalled iTunes too, did nothing. The exact same old iTunes playlist comes up in Traktor.
