Macbook pro 13, traktor scratch pro 1.2.6., NHL Kontrol x1 mapping

Can someone help me. A while ago, i dont know what i did, but now all of my kontrol X1 led are not shining at all when not pressed( the off state). Even if i set the off state to 50 % nothing at all. On the on state everithing works fine! Has this something to do with the mapping, cause im running a custom mapping, i did try the default mapping but it was the same. So any help would be apreciated.
