Reply to Traktor 2.5.1 and LPD8 issue

I am new to mapping but am trying to get my Akai LPD8 to do what I want.
Nothing fancy but the issue I have is that when I program the pads in controller management simple things
like play and pause work like a charm.
I shut Traktor down... reload my mapping... the pads don't work.\The knobs still work just the pads don't.
I go into the manager and re-learn the pads... they work like a charm again.
Since I really don't wanna have to do this all the time.. what am I doing wrong?
Any help appreciated at this point.
