Since the import dialog box was returned to it's former state, everything else is working as it used to, except now Lens Profile Correction is being done to raw files during import. This isn't a terrible disaster, in fact it's most likely a good thing, but I don't know how this got set in the first place, and how to disable it during import if needed. Any ideas? Is this happening to others as well?

Does Enable Lens Profile Corrections in the Lens Corrections – Profile tab have a checkmark after the import or not? If not, is there an i in a circle which says a built-in lens profile has been applied?
Yes, the checkmark is there. It's done automatically now, but it didn't use to be, and I haven't changed anything in that regard.
