Devo 7E channel mixup

So I bind my Devo 7E Mode 2 Deviation ver. 5.0.0 to my acrowhoop FC with DSMX/DSM2 and in betaflight when looking at the receiver my throttle is working properly but AIL/Roll is mapped to the RUDD/YAW channel and neither of the other channels work at all. So when I move my sticks the only response I get on my receiver are throttle and roll. I've tried using the mixer to remap all of my channels but I still get no response at all on channel 2 or 3 can anyone help?
