Fs painter AI traffic models.

Gentlemen / Ladies,Fs painter AI models seems to deploy the thrust reverser and spoilers during the descend phase of the flight keeping it engaged all along, and through touchdown the condition continues. After the touch down roll the nose pitches up few more degrees , settling the nose wheel quite awhile later for a long pitched up touchdown run, and finally it deactivates the thrust reversers and spiolers when the speed reduces during the run.The models are utilized with Ultimate trrafic AI program, other AI aircraft does not exhibith this kind of behaviour with Ultimate trrafic.Any way to fix this condition? must it remain as is?.Thanking You,Best Regards,Aftab.
