ATR 72 (Microsoft) ignition wont stop after starting engines? A bug possible?

After i started the engine you can still hear and feel the ignition going on. Even if i use auto complete the problem appears. To make sure its not a general problem i tested several prop planes (Caribou, An2, DC3, Ford Twin and some others) but it only appears with the ATR planes.
I can only avoid it if i put the plane directly to rwy. If i hit Start1 Button then it starts too.
I fly and during flight i could not hear it but right after landing it starts again.

No one has an idea or know what the problem is? I am testing it today too. I use auto complete checklist with official checklist and after starting the engines the hickup with ignition starts and i tried so many things but could not solve it.

You said in other Thread you have FS Realistic running and it stops if you turn FSR off. Seems related?

I asked this in another thread (were this has been merged) too but no one seems to see an connection. And if its a FSRealistic thing which is possible why it does not occour when i put the ATR directly to rwy? Thats why i dont think it has to do with FSRealistic.

Have you tried it with FSR uninstalled? The first step is always to have no Mods or third party software running.

To test it i can just turn it off. But i can also enable single aspects like that one i tested. But still i dont understand why this phenomen did not occour when i start directly from rwy?

That’s a question for FSR. Maybe there’s something they don’t do if the plane is not Cold & Dark.

I just contacted their support and request an update for this app. But since the ATR got an update too i guess that is the reason. They changed something so the FSR App wont work properly any longer according to this aspect.
