It looks like you might be cutting through the Gyp layer of an interior
wall, although I would expect that to show up on screen as well. Check the
plan and try shifting the section cut or turning off the interior workset,
if it's set up that way.

Thank you for responding MJ. There is no ACAD file in this at all and this
isn't an upgrade, it's just 9.1. I went ahead and tried turning off all the
Imported Cat. and there was no change. I'm at a total loss of what this
could be.
