Unable to calibrate radio

I have a “Turnigy i4X 4-Channel 2.4GHz AFHDS 2A Transmitter With Receiver” and a pixhawk 1 board. When I go through the calibration process, everything works fine until it hits the radios. It recognizes the receiver. When I move the sticks to calibrate, nothing happens. Is the receiver correct? Or is there something else? I’m using QGC on a Mac
