Rekorbox Exportmode

I use  RB 4,1 in exportmode with CDJ 2000 NXS 2 & DJM 900 NXS 2 and SP1. When SP1 is Connected to the usb port on the player. It works good but the problem is the channel 1 and  2 on SP1 is reversed and not in sync with the players channel 1 and 2.

I think this could be solved by a new firmware on the SP1 for RB.

Please forward thie to the engineers.
