Landscape Splines Subdivisions

Hello,

I have a little issue with subdivisions of Landscape Splines. I hope someone can help me.

  1. Landscape on the left was created with a scale of 5,5,5
  2. Landscape on the right was created with a scale of 100,100,100 then scaled down to 5,5,5

Now if I use Landscape Splines on these landscapes I get different results in case of spline subdivisions.
It looks like the splineresoluition gets set when creating the landscape. Is there a way to change this afterwards?
