Focke-Wulf Fw 200 and hughes h 4 hercules Autopilot wobble down and up!

Good day !

In MSFS 2020 i have problem with Focke-Wulf Fw 200 and Hughes h 4 Autopilot every time when turn on AP of the airplane wobble down and up , same on AP in Hughes h 4 !
No matter what i do AP do same thing , Up and Down , up and down not stable every time when is turned on ! The problem began over 2 months now is the same .

I try do delete and again download the add-on but when fly AP again the same ! Cant fly !

i have steam PC version msfs 2020.

Do those have autopilot?
Or is it a mod (community folder)

Yes they have , but autopilot is broken …

Any idea how to fix autopilot ??
