Loading Sundowner first and then going to Default C172 causes issues with aircraft

[azpilot61]

So I've been flying nothing but the Sundowner the last few days, then this morning decided after loading the Sundowner first to change my mind and load the default C172. Once I did this I noticed that the items using custom datarefs IE: Course knob, Barometric knob etc. did not work in the default C 172 This was on 12.1.2r4 release of X-Plane

So I loaded up the default 12.1.1 X-Plane with the Sundowner and of course the default C172 G1000 and did a test

Loading up the default C172 first everything on the G1000 worked fine all knobs turned and changed their respective item IE: Baro, Course etc.

I then loaded up the Sundowner. The Baro didn't work at all on the sundowner but the course did and the other few items I checked did as well so far.

I then went back to the default C172 and the Baro and Course stopped working at that point. I then loaded the default SR22 and it was broke as well.

The only way I could get those items to work is to shut down X-Plane and restart and use the default C172 or SR 22 first if I wanted.

Something with those custom datarefs or something else with the Sundowner is still not correct for the G1000
