Overview: Identifier numbers in the FOLIO instance display do not have the correct labels. For example, some are being labeled as ISBNs when they are definitely not.
Steps to repro:
1. login to FOLIO Stable, go to the Inventory app
2. Search for resource title: 'Modern Irish Lives' (s.indexdata.com/inventory/view/e59a7acb-bc7c-4e53-89d6-addc55826999?filters=&query=modern%20&sort=Title)
ISBN 0717127869 - 10 digit ISBN numbers.
These identifiers are not ISBNs, except maybe the first one. Either they are mis-formatted, or they may be missing leading zeroes. It would be helpful to see the original metadata underlying this instance record. The third one is the LCCN. Not sure what the second one is.
Additional info: wayne points in the direction that this is likely an issue with the old MODS data loader
