Procedural foliage tool scattering foliage on static mesh

I tried the feature in both 4.19 and 4.26 both are giving the same result.
I disable the static mesh option in procedural foliage volume but it’s still adding foliage on the static mesh.
I know about foliage block volume but I have a lot of meshes and don’t want to spend the time on adding blocking volume for every single mesh on the scene. I also know I can erase foliage by using the brush tool after spawning it procedurally.
But I want to know if there is anything that I can do to make it work correctly.

I’m curious about this too. Having the box checked and unchecked seems to do the same thing.
