M-Audio Axiom Pro 61 after touch

Hi

I have an M-Axiom Pro 61 & Cubase 7.5 but I have an issue with after touch, its keeps sending data while im recording and messing with the track, no matter how I adjust it, nothing seems to work, its keeps on adding after touch data.

please tell me how i can disable the after touch, so that i can be free to record without any added after touch midi data so i can play uninterrupted.

thanks
