Problem with xdj r1

Here is the problem :
1- Virtual DJ 8 Deck A and B go simultaneously to CH1 and CH2 from XDJ-R1 and CUE 1 and 2.

2- Deck A only goes to CH2 and CUE2 of XDJ-R1.

3-The buttons "track search" don't work on CH1 and CH2

It is impossible to mix and preview songs. 
I try rekordox from a another PC, same problem.

Software XDJ-R1 : VER 1.13
VIrtual DJ8

Thanks you for helping me
