Problems with throttle control on specific cracked-planes

[McDonnellDouglasFanBoy]

So, I've downloaded the A319 from TooLis and also the Rotate MD-11 which happen to work just fine, but I have a problem with the throttles where I have to manipulate them manually by mouse instead of control. I have re-calibrated my controls and the throttles still don't work for this MD-11 and A319. My real life throttle does work with other planes in the flightsim except these ones. I should also add spoilers and reverse thrust doesn't work for the MD-11 and specifically the MD-11. I've also had this problem with some other Airbus addons. If anyone has the same problem or knows what the problem is, please let me know.

Edit: The A350 also does the same but in a more weird way. When I move the throttle to full thrust, it gives me an alarm in the cockpit but doesn't do anything nor do the throttles move in-game.
