Zones don't work

Hello, zones don’t work, I’m attaching screenshots, no matter what I do on the slider, it doesn’t react at all. please help. sketchup version 2023, latest skatter version.

What are the dimensions of the surface?
Have you tried increasing the “Size” parameter of the zones to a much larger value?

surface size 50m x 50m, and yes i tried increasing size param from 1cm to 10mln cm, not responding, pc spec: intel i9, 64GB ram, geforce RTX 3090, win 11
