PX4/QGroundcontrol not recognizing all radio transmitter switches/dials

Hello,

I cannot get Qgroundcontrol/PX4 to recognize all the switches/dials on my Radiomaster Boxer radio transmitter. The receiver is a Radiomaster ER8. It is connected to a Pixhawk flight controller through the ‘RC IN’ port.

When calibrating the radio, I can successfuly map the two joysticks, however when the calibration process requests me to move all the other switches/and dials, it only picks up one other switch, and only two positions of the switch.

How can I get PX4 to recognize all the switches/dials on the transmitter?
