Reply to Numark mixtrack Pro Play button delay??

Hello!

<--- new to this community .

I am sorry if this is in the wrong section of the community s.

I have a Numark Mixtrack Pro and I am quite new to mixing. But I have a problem with it

I have it set up with Traktor Pro 2.

Problem: The play button on the right deck (Deck B?) is somehow set up different then the left one
On left. it works great. track starts play'n as soon as i press the play button
The right one on the other hand does not play when i press the button but only plays as soon as I release it again.

meaning as soon as I click it and release it's never on the spot .. I can basically press the button and hold it for as long as I want and the track wont play untill i let go of it.

Any ideas on how to fix this? :/
