DJM 900 and Traktor Scratch Pro 2 - Wrong Deck Plays?

Hi there!

I have a 900 Nexus and 2 CDJ-2000s (connected to Channels 2 and 3 on the 900, with nothing connected to Channels 1 and 4).  I am using Traktor Scratch Pro 2 as well as a Native Instruments Kontrol X1 controller.  I run the setup wizard in TSP2 and set things up as 2 Decks (Scratch).  Also in the Pioneer utility all four channels are set to USB input and Channels 2 and 3 set to CH2 Timecode Digital and CH 3 Timecode Digital, respectively, on the mixer output tab.

Here's my issue.  Within TSP2 when I play CDJ #1 (on my left, connected to channel 2) via a timecode CD its meter starts to show colors but Deck B (the one on the right) starts playing, not Deck A!?!?!  When I play CDJ #2 (on my right, connected to channel 3) nothing happens... 

When I'm in the preferences for TSP2 it shows meter activity on both channels, however, and it shows that both timecode CDs are sending a signal.

Can someone PLEASE help... this is driving me nuts.  :(

Thanks,

Keith
