CDJ-2000NXS2 auto master not switching (with DJM-900NXS2)

Hi!

I have two CDJ-2000NXS2s (let's call them A and B) and a DJM-900NXS2 mixer, and I have noticed that the master only correctly switches in one direction.

The problem scenario: B is the master, I bring a track on A into the mix, and then I bring B out of the mix. A should now be the master, but I have to do this switch manually.

What's interesting is that, if A and B are reversed in the scenario above, everything works properly. I have updated the firmware on both decks to 1.85 and the firmware on the mixer to 2.07. This issue is really bugging me, and any help on resolving it would be greatly appreciated!

Thanks,

Teddy
