GeoPak Drainage - Nodes in Profiles

When I generate a Drainage Profile, I see that Library items from my DOT show up with the appropriate width and invert drop across the structure. The nodes that I create myself, however, show up as straight lines with no elevation drop. I've looked all over and through as much of the documentation as I can - where does one specify these parameters?

 

Thanks,
