New to traktor. How would I connect 2 Xone K2 controllers alongside my X1MK3

I just got traktor 4 and seems after I import the K2 mapping for my 2 Xone K2 controllers, it still doesn't read the K2, but it reads the X1 MK3 just fine. My question is, how the heck do i use all 3 controllers?

I downloaded a k2 midi mapping for traktor, and when i import it, i lose my x1 control. I would like to have all 3 mapped, even if they over lap its ok.
