Snap to Ground not working?

[maf1909]

I've noticed an issue lately with some models I import where "snap to ground" doesn't snap the object to the ground, but lifts it above the ground a bit.

This model is a random model I downloaded off grabcad as an igs.  Imported using the "keep original" location (although that doesn't seem to make a difference), and added a matte white material to a ground plane.  When I click snap to ground, it lifts the model above the ground, and I have to adjust it back down manually.  Is this a bug, or am I doing something wrong?

If you are on KeyShot Pro you may want to open up the geometry editor and look at the bounding box of the object.

interesting, didn't know that was a thing.
