Mode1, not model 1. It's in your control mapping where you can see the numbers changing as you press them.
What can happen is you can map a mode, and just that mode, so that your pedals are set up to run as the rudder controls. However, if you map mode1, but switch to mode 2, 3, or 4, you won't get a reaction/response. It won't be mapped even though it's still recognizing the hardware. It just doesn't do anything about it.
There is a checkbox on that screen that says something like: "Automatically choose mode?" or "Automatic mode switch?" (I can't recall which). when this happens you can change out of the mode you want depending if you take a GV, bomber, fighters class of plane.
