Hello,
I have just joined the forum to report I have the same problem, the sound of the headphones will come out through the master signal.
I have recently purchased the Full version of Cross DJ and I am rather disappointed with this problem. From what I can read in this forum , the glitch has been around for a while.
I have a Nexus 10 tablet which runs Android 4.2.1.
I have purchased this cable: Griffin DJ 2 Cable:

I select one track , click on the headphones button, and play the track. The sound can be heard through the speakers. I tried the option "invert master and cue outputs" but it did not work. I played around with the Mix and Vol knobs, trying several combinations, but I did not matter.
The only way I can stop the cue going to the speakers is by turning the gain of the deck down to zero, but then, alas, I won't hear nothing through the headphones - not even with the headphones button on and regardless of the postions of the mix and vol knobs.
Has anybody actually manages to pre-cue with the android app?

Edit: I tried to locate the serial number in the app but I can't find anywhere. I do have the order reference from Google Play.
