deck c button switches and won't work

i just finished my arcade mod and firmware update recently and i love it.

i am having one problem with it that is confusing me. while i am using the controller, in a random amount of time each time i use it, the deck c button will activate itself and won't let me switch it back. it doesn't fix the problem when i turn the vci off or close traktor. traktor would have to be off for a while for the problem to go away.

any help is appreciated

thanks,
edsel
