Newspaper issues sequencing out of order after ingest

We are guessing that we might have had more than one Newspaper issue ingest job running simultaneously. The two jobs might have been ingesting TIFFs for the same title but for different issues. We are guessing so because we now see issue sequencing problems when we use the Prev - Next buttons in the Newspaper interface, The issues shown jump back and forth from issues in one volume to issues in a different volume. Examining the RELS-EXT shows the the "sequence" number was assigned to each issue as it was ingested regardless of its date or volume number. Apparently issues need to be ingested in exact sequence or the sequence number written to RELS-EXT gets screwed up.

Anyway, is there any known way to fix the Sequence numbers in the RELS-EXT or is a re-ingest of these volumes and issues in exact order the only way to reasonable fix this?
