Thematic height doesn't work with specific files in CONNECT

Hi all,

I have a problem with displaying the display style > thematic height in MS CONNECT 10.03.00.30

When I want to use the display style > thematic height in with a Point Cloud in MS CONNECT 10.03.00.30 no colors are visible (first picture). When I open the same file in V8i SS4 everything works fine (second picture). Could this be a bug or did I missed something?
