channels of transmitter in the wrong order and one missing

Hi everyone!

I recently purchased the

Turnigy IA10B Receiver 10CH 2.4G AFHDS 2A Telemetry Receiver W/PPM/SBUS

I paired it with my Turnigy 9x (8 channels) transmitter and when I plugged in my servos and other motors I found out that the order of the channels in the transmitter doesn't correspond with the order of the channels in the receiver. The channel 2 in the transmitter worked when the motor was plugged in the channel 5 of the receiver, and so on for the other channels except Channel 1, right stick, direction up-down. It doesn't matter which channel in the receiver I plug the motor into, channel 1 in the transmitter seems to be missing. Can anybody point me in the right direction? Thanks!
