This is known. And it is really not a problem but a feature :-) The
patented algorithms that computes the isosurfaces for structured
datasets can also compute normals. If use any other algorithm or input
type, no normals will be generated during isosurface computation. To
get smooth shading, you have to apply the normals generation filter to
the isosurface.

This is a known problem and I believe is in our list of things to fix.
