I tried to make several updates to this https://folio-snapshot.dev.folio.org/inventory/quick-marc/edit/2ebdbdec-0294-4f59-ba0e-1ac70ca338d8?filters=source.MARC&sort=title
AND I got this message
But the changes actually saved! Very odd. Note that this record had these fields checked on the Instance record: Suppress from Discovery and Staff Suppress
Once I disabled those fields then I no longer received the error.
