The wheels contact bug it's a very well known bug that dates FSX, and it was never addressed in P3D, which has exactly the same bugs and it happens with the default jetways on default airports too. Try any default airport with jetways, maybe with an airplane with doors a bit lower than usual, like a CRJ: the wheels will sink too.
Why you think SODE was made to begin with ? Why you think many developers are switching to it to do jetways, if the default system worked flawlessly ?
