You have to set the controller in the main dropdown menu to your joystick which controls pitch and bank. This is mandatory. Try to choose anything and then go to the axis section and notice that you have no choice which controller is set to pitch and bank.
The fact that your device order is keyboard, Saitek Rudder Pedals, Thrustmaster means I know for a fact that your trigger on your joystick is Button #33. That is because that is the first button on the second controller. What you must do to get the Thrustmaster Combined controller as the first controller. Then trigger will be Button #1 and not Button #33 and everything will be fine.
Go into your devicesorting.txt and delete all lines that aren’t the rudder pedals and thrustmaster controllers. Edit the file so that the top line is the Thrustmaster and the second line is the Saitek pedals.
When that is done your drop down menu will be Keyboard, Thrustmaster, Saitek in that order.
