Rhino messes-up geometry in Blocks

When I make a block out of an imported asset, Rhino does something with the block.
This is an example of a shaded view where the block [ on top ] is shown as in wireframe vs the geometry of the asset [ on bot ].
Part of the block geometry doesn’t even render.
Is it possible that Rhino flips some of the faces when making a block?
This is not isolated, it happens often.
