Reply to Songs start to jump!

Hi!
Hope you will understand my english...

I have a big problem with my controller. When I scroll through the tree list, my songs start to jump when I press the shift button and turn the round button! only when shift + round button is used.

I've tried to delete the mapping. Installed it again without any help ...
I have tried other mappings but with the same problem.
I have deleted traktor and installed again. but still the same problem.

So it looks like there is something wrong with the controller and nothing wrong with the software that I have used.
