Problem importing OpenSCAD STL in HeeksCAD

Every STL produced by OpenScad I try to import in HeeksCAD results in the same result: either it doesn't display or I get artifacts. Other STLs work fine. What am I doing wrong?

My own objects don't work and neither do other people's objects. I tried to import the STLs for Prusa part and they give the same behavior. I'm using HeeksCAD 0.18.0.

I can't import OpenScad stls anywhere too. The only program that accepts them is Blender, so I import stl to Blender, then export, and exported stl can be used anywhere.

@DeltaFlight thanks for the tip, I'll give this a try.
