Extrusion of holes

I try to make tree linear extrusion holes. Hole 2 and 3 work ok. Hole 4 which should be equal to 3 is "rejectet" (Volume body remove 4mm)

The hole would create nonmanifold (zero-thickness) geometry, which our geometry kernel doesn't allow. You can see it in the error visualization.

You'd need to either move the hole, change its size, or change that counterbore depth.

After spending hours trying, I switched Language to English. I was successful. Strange.
