[ORD 2022 R1] Create Cut Fill Volumes not following active terrain

I have a project where Create Cut Fill Volumes is not working correctly.  It seems to be using a different existing ground terrain than what is set as active.  The corridor correctly ties down to this terrain.  The first image shows the left side of a particular template drop, which is a correct representation.  The second image is of the same left side, but with the cut and fill shapes displayed.  For some reason it appears to be using a different terrain.  The cut volume doesn't extend to the existing ground over the entire section, and there is a phony fill volume that doesn't really exist.  This is happening on most, if not all, of the dynamic cross-sections.  As a test, I loaded any and all project-related terrains into this view.  None of them represent the surface that Create Cut Fill Volumes is using.

         

What is happening here?  Needless to say, at this point I have very little confidence in my earthwork volumes.
