Crossfader issue with DDJ RX and Rekordbox 5.4.3

Hello all,

I have an issue with Rekordbox 5.4.3 and DDJ RX Controller, and i don't know if it's a bug or a bad configuration. The problem is with the crossfader.

I put the crossfader to the right only a little bit (he first line):

But Rekordbox put the crossfader totally to the right:

The same problem if I move the crossfader to the left:

I try to adjust the crossfaer curve in the controller and don't work (it seems thaht it does not do anything). In previus version of Rekordbox works perfect (and I don't make any updates of the firmware, windows, etc..). It's a bug or bad config?

Can anyone help me?

Thanks

Pablo
