GNS430 RNG buttons inoperable and FMS / progress fuel not synchronised / AP alt set knob

gearup

XBOX X Fs24, GNS430 range buttons do nothing only 5nm is available. Any clue?
edit: VLOC input seems to be broken as well I cannot input ILS frequency.
Supposedly it is my mistake but my FMS progress is counting down from the full tanks range and endurance instead of real quantities.
AP Altitude SET knob key bindings ( decrease/increase autopilot reference altitude) dont change reference alt - instead plane just try to pitch up or pitch down after using these keys.

Thanks in advance.

I've heard a few complaints about this recently in many aircraft, including default ones. I think Asobo messed up some interaction code in their last update. Since I believe this is squarely on their side of things, I haven't gone looking for a solution yet, as these things often clear up quickly once they are reported.
Since you say it's supposedly your mistake, would you mind sharing what that mistake supposedly is? Perhaps I can confirm whether that's the intended behavior.
Here is the relevant FAQ from the manual:

Why is the autopilot behaving strangely with hardware inputs?
In order to implement altitude & VS preselect and more advanced features in the easiest way for cockpit builders to access, external hardware must use the HTML events described in the
“Instrument Events” section of this manual and NOT the native autopilot events.

Let me know if there is anything else I can do for you!
