Sampling

To whom can help,
I have some question regarding sampling on the mixvibes DVS pro, I understand from the manual that when a loop is running on the mixvibes media player if i am to push send the loop would be sent to a sample pad, now it is sent to the pad but it would be cut short or more than what I set as a loop, it will even sample from a part that I did not set as a cue point, what am I missing here?
