Cross Sections omit Existing Surface

I'm using InRoads Suite V8i (SS4) 08.11.09.878 inside MicroStation V8i (SS4) 08.11.09.832 product.


I'm creating Cross Sections from one of several models.
The dynamic cross section viewer shows the existing ground line just fine.


I get the sections printed to graphics but always without the existing ground surface line.  All levels are displayed.  I get all the other graphics I requested, but not the existing ground line.


Why does the existing ground line not show up?  I cannot calculate volumes this way!


What items shall I check / how to resolve?
