How to get rid of runway- and taxiway bumps to avoid penalization when rolling o

[camaflight]

Even default aeroplanes make jumps at the very same spots. But one add-on plane did only a minor jump and by some speeds not at
all.
So I decided to give adjustments of the contact point part of the cfg. I only adjusted the three variables:

Static Compression (feet) (0 if rigid)
Max/Static Compression Ratio
Damping Ratio (0=Undamped, 1=Critically Damped)

It was possible to damp the jumping, but aparently it does not solve the basic problem. These kind of jumps only ocurs at some airports,
so maybe then, it is some weird combination of scenery bgl,s and aircraft cfg and air-file that makes it. ????

Sometimes we can even see AI-planes making such jumps.

I wonder what causes it and what could be done to solve it...
