error in chop shop with new os??

I chopped up a sample....assigned it to 16 pads..and i thought everythig was ok. when i started makin my beat, i noticed that when im hitting a pad when another sample triggers, the sound that is recorded gets cut off...All the samples are recorded on seperate track...but im not understanding why its cutting off the sample....any got any ideas?

Polyphony?

Got to param in the program screen and set it to mono instead of poly in the top right corner
