I have gone back to the two original multi-source files and examined the SU table.
I have discovered that for both observing dates, RA/DECAPP = RA/DECOBS, and these
are different from RA/DECEPO.

I have examined other EVLA data I have on disk from two other programs and encounter three different cases; some like the above, some where RA/DECOBS=RA/DECEPO, and finally the case where RA/DECOBS=0.0

The others were high-frequency data that did not require PBCOR so I never encountered any manifestation of this until now.

Might the problem be originating in Obit? I know there should be ways to extract information directly from the relevant ASDM tables, but I don't know how to do it.
