Rekordbox 4.0.5 problem

Hi everyone,

Since the last update of rekordbox, I have noticed a failure in the program when I connect my DDJ RX. The high knob (EQ) of the channel 2, the center isn`t calibrated well. Only happens in the channel 2, in the others channels works well. 

I rotate the knob all the way left and all the way right, and is calibrated well. The center is the only problem.

I tried to reinstall rekordbox, but the problem persists. Someone has the same problem in the DDJ RX???

I attach a photo:

In the controller was exactly in the middle, but in the software was moved slightly to the left.
