Honeycomb Bravo Autopilot knob not recognized

[Carleightysix]

I'm having an issue with my Honeycomb Bravo throttle quadrant. Specifically, the autopilot knob isn't being recognized by the plane in my sim setup. Everything else seems to be functioning fine, but adjusting altitude through the knob has no effect. This issue does not occur with other airplanes.
I'm using MSFS 24 on a Windows 11. Has anyone faced a similar issue or has any ideas for troubleshooting? Any help would be greatly appreciated!

Thanks in advance!
