Reply to Numark 4Trak Cue problem...what am i doing wrong?

Hey folks. New here. Long time lurker, first time poster. Been an audio engineer/producer for quite a while and always dabbled with DJing...but finally leapt into my first decent controller for Traktor. Lo and behold, the 4Trak.

Ok, so after setting up all the routing and configuring some custom maps, im left puzzled by the Cue controls. Every other mixer/controller ive used functions where you turn the blend knob to CUE...you hear the tracks that arent playing yet....and when you slide the knob towards PGM, you blend in the main mix. Right?

Not so on this. When i turn the knob to full CUE, i still hear the main mix. Not as loud, but its still very apparent, and is getting in my way.

What am i doing wrong?

Thanks in advance.
