Flight Controller not Switching Flight Mode with Mode Switch

My Mateksys F405WingV2 will not change modes with the switch on the transmitter. If I go into “Flight Modes”, and flip the Mode Switch, the correct mode is highlilghted and the PWM rate changes, but the mode does not. The mode doesn’t change on the HUD either. I can change the flight mode with the Action menu, however.

I am using ArduPlane V4.6.3 (3fc7011a)

Some flight modes need GNSS signal, or other pre-conditions.
If the pre-requisites for entering a flight mode are not met, it will not enter it and ignore your command. This is normal, expected and desired.

@Rinomin As long as you haven’t armed yet, you can switch between all modes in Arduplane to test the settings, even without a GPS fix. You won’t be able to arm the system at that point. However, you shouldn’t disable the preflight checks!
