CaptainSim 777-300ER steers left after landing

Have been experiencing this issue. After touchdown with 777-300ER the aircraft pulls left. If trying to steer back right, it won’t do a thing. Always ends up on grass.
And no, this is not a problem with my landing skills. Don’t have this kind of problem with other larger aircraft such as A330 or 747. Is this a bug or something to do with my joystick with this particular plane?
I’m using salty dev mod.

No this also happens to me too & I use default Xbox one s controller. And I’ve a question, when I’m using the CS 777-300er while taking of it steers to the left & right for no reason and it is hard for me to takeoff and then I takeoff from the grass not the runway… does this happen to you too?
