Hi Jens,
I also found this problem when I first tried this in HID mode. There are two options for you....
Update the traktor software the the newest version (available through the traktor service center)
Use your current version of Traktor and you will find that if you use the rotary selector like you are doing and also the fwd/reverse track buttons on your CDJ to scroll through tracks (above the CUE button). I found this weird though so would recommend the update on traktor software.
Hope this helps.
Dave
