A recent commit added logic to the export code to add date:inception_lower and date:inception_upper properties when an edtf:inception date is present.
I think this should be edtf:inception_upper and edtf:inception_lower, instead, to be consistent with the other date properties. If so, I'll file a PR with an update and catalogue the new props in the properties repo.
