Reply to Traktor DJ Won't Sync With Traktor Pro

Can anyone help me? I'm using Traktor DJ on an iPod Touch and I can't get the beatgrids or cue points to sync with Traktor Pro 2 on my Mac.

Everything seems to be set-up correctly. Drop box updates every time I close either application, but nothing ever updates on Traktor Pro or DJ.

Any ideas?

Edit - I should add that I've tried locking the tracks. I've tried not locking the tracks. I've tried updating cue points on the mac then checking on the ipod, plus the other way, nothing ever updates. iTunes Match is turned off.
