M-Play as Faderwing

I have boght a M-play to connect with my M2pc, for usa as a faderwing for the Martin M2pc controlsurface!
But whwn i connect the M-play, it dosent seem too work properly.
The software finds it, but only the buttoms work no faders work!
When i save a Cue on the first fader on the m-play, it is stored in bank1 and subbank 13 Why not 11 !
What have i done wrong??
