Contact pair search broken for surface geometries

[FEAnalyst]

Hi,

it seems that the contact pair search is broken for surface geometries (in 3D and 2D model spaces). The following error appears:

The same happens when surfaces are positioned one above the other.

I tested it in v2.4.0 and v2.4.3.

one other strange thing is when I went to select parts to assign meshing parameters it highlights all of the parts but doesn’t select them all if that makes any sense. I have a screen capture somewhere showing it.
