Thanks. I’d like to fix it but not possible atm.
Anyway in MSFS I don’t have a problem with the devices.
Yes, while you can work around this to some extent following a process it’s also a bit frisky at times.
It’s still buggy as that’s a workaround to a core issue incorrectly handling duplicate devices in the sim.
Technically, the workaround process laid out here should also work with Aircraft Manager, but it’s still touch and go imo if you accidently change something.
Try it and see?
