AutoCAD Civil 3D :: Hatching In Profile View

I discovered a weird thing that seems like a bug...I tried to hatch manually while in profile view (couldn't figure out how to do what I want with the profile view hatching options) and it seems that if I try to make one hatch (by picking internal points) that includes multiple structure profiles on the same profile view, the first structure profile for that profile view works as a hatch boundary, but subsequent structure profiles are basically ignored if I keep trying to pick internal points to make a composite hatch.

I assume it's because of this same bug that I can't create a hatch by choosing boundary objects and using two structure profiles in the same profile view as boundary objects.

how to hatch using the profile view hatching and to use a pipe network as a boundary, that would also be useful.

if I hatch by picking internal points, and pick one area with a structure profile as part of the boundary, and then I pick a similar area in a different profile view, everything works fine...it's just the second (and though I don't have more than 2 structures per profile view in my drawing, I would assume any subsequent) structure profiles that I try to use as hatch boundaries that AutoCAD is basically ignoring.
