Incorrect holdings reported under some circumstances

Consider the record at https://lehigh-test.folio.indexdata.com/inventory/view/05b00ede-c4c3-41b6-8281-0d8b34ad031c?qindex=hrid&query=973028&segment=instances&sort=title for Calls and responses :, the American novel of slavery since Gone with the wind by Tim A. Ryan.

• It has a single holdings location, Linderman 2nd Floor - Rotunda
• That holdings location has a single item, with barcode 39151008889483

We can view this record in SRU, using an HRID search, at http://lehigh-z3950-test.folio.indexdata.com:9997/sru?version=1.1&operation=searchRetrieve&query=hrid==973028&maximumRecords=20&recordSchema=opac

• It has a single holdings location, Linderman 2nd Floor - Rotunda
• That holdings location has a single item, with barcode 39151008889483

Just as we would expect. But consider the following SRU search: http://lehigh-z3950-test.folio.indexdata.com:9997/sru?version=1.1&operation=searchRetrieve&query=title=gone%20with%20the%20wind&maximumRecords=1&recordSchema=opac

• It finds the exact same record, with HRID 973028 (visible in control-field 001)
• Its holdings location is Library Materials Center (LMC)
• It has two items in that location, with barcodes 314223-1001 and 314223-2001

Clearly the wrong holdings are being associated with the record in the second case.
