ATR reference altitude key binding issue

Hello.
Small question for ATR pilot, I have bind the altitude selector (auto pilot) on a wheel of my joystick. So the up button is binded on “increase reference altitude” and the down button on “decrease reference altitude”. It works great on all plane but I have a problem with the ATR :
If the autopilot is on ALT mode (so it reach is altitude and keep it stable), if I use my joystick wheel, the reference altitude is well changed, but the aircraft will automatically trying to reach this new altitude (so I can not plan the descent in advance). If I use the selector on the autopilot panel (and so using my mouse to change the reference altitude) the reference altitude change but the aircraft keeps it current altitude. Is there another binding for selecting reference altitude on the ATR ?

I want to be able to change the reference altitude with my joystick wheel but without trigger the AP to reach this new altitude.

Thanks

Beware setting lower alt target before vnav is very close to TOD. Doing so pushes TOD way out, at least until an update fixes it. Better to not set alt target until you have the magenta box next to the altitude tape.

Yes I change the reference altitude when I’m at less than 3nm from TOD.

But at any moment (even during cruise when ATC ask me to change altitude), if I use key binding (event the default CTRL+PageUp or CTRL+PageDown), the ATR try to reach this new altitude directly. But if I turn the knob on the Autopilot panel with my mouse I can change the reference altitude while keeping my current altitude.

I also have a problem with my new Honeycomb Alpha, external lights binding doesn’t work.

It seems the ATR, even if it was made by Asobo, has a lot of binding bugs
