Today update - game destroying bug or am I doing something?

I went to General/flight model and the screen was totally greyed out. It did show flight model as modern but there was no way to change any of the parameters on that page. All the other pages seemed to be fine. I don’t think this right but does it have any bearing on the problems?

2 days later - went back to gen/flight model and page was as it should be. Also found one of the up/down control axis on the yoke had the “reverse” box ticked so I untucked it. I also went to data and flipped it off then on.

Planes seem to be flying ok now. The baron had the nice nav with the key pad and no soft keys. Now it has the nav with the soft keys and needs the knobs turned (a pain). Do we get to choose which nav?
