Reply to Traktor 2 cueing problem

Basically i believe i have set it all up correctly i am using traktor pro 2 and a hercules rmx controller but basically the sound thats ment to be comming out of the speakers is comming out of the headphones and vice versa.

So when i do a transition you can hear it change in the headphones but doesnt change out of the speakers

How do i change this?
