Probable you are setting joystick/rudder... axis in KEYS tab instead AXES tab.
SAVE AS allow you create a joystick profile for specific aircraft and LOAD this profile before fly in then.
Spitfire/Hurricane need a difference "CEM" settings than Bf 109 - in this Propeller Pitch adjust work in inverted way.
This settings (SAVE AS) can be load include during flight.
