ur824 - how to route two stereo tracks out?

hi, i’m currently playing around with the traktor dj program and i therefore want to have two stereo outputs: one for deck a and one for deck b.
my interface is the ur824, which i’m very happy for, except that i can’t seem to configure it to route outputs 1/2 and 3/4 into my hardware mixer propely. when playing in traktor only the signal from 1/2 is routed through, while 3/4 remains silent. traktor is set up to send a to 1/2 and b to 3/4.
in the dspMixFx_UR824 i have these settings:

LINE OUT 1/2 -> DAW Out 1/2
LINE OUT 3/4 -> DAW Out 3/4

do i need to do anything else?
if someone could point me in the right direction, i’d be grateful.

Did you ever figure this out? I am dealing with this now and it currently looks like there is a problem in the DSP mix that does not let you use the Line Outs unless you are in Cubase.

It works in cubase without using the DSP. Maybe it is the configuration of outputs from your DAW?

I don’t know. Sorry I’m not much help…
