To fix that you want to change the stick scaling plot not the damper setting. I did this so long ago that I forgot how it works but it's something like dragging the points of the scaling plot so that at low stick deflection the stick scaling is less sensitive, i.e. near the center a medium movement of the stick creates a very small movement of the control surface. Your scaling plot should not be a straight line across the top at 100%; it should be down around say 30% on the left rising to 100% on the right.
