FS24 FBWA32NX engine bug - pls help

Hey fam,
rather dissatisfied with the Fenix' performance on my machine in the new sim I checked out the FBW A32NX . Unfortunately I ran into a rather stupid bug (which, frankly, does not completely prevent me from flying, but is a nuisance).

Soon as I start the APU the engine 1 knob would switch on. Whenever I try turning it off it would turn back on within 0-1 second. Be that as it may, I'm thinking. Why not start the engine 1 first then, eh?

Here comes the second problem: If I turn the engine mode selector to IGNITE and switch off+on the engine 1 knob, the engine will take forever to start. I'm literally talking 2-3 mins here until I get an avail message. Same would then apply to engine 2.

You thought that was enough? Let me surprise you. With both engines running at norm N1/N2 levels, soon as I turn off APU and set engine mode selector back to norm the engines would just shut down.

Something's not right here and I've done anything that comes to my mind possible. Hopefully some of y'all have an idea.

Thanks in advance
