found multiple recordsets with name: %s, expected 1

Error message

found multiple recordsets with name: %s, expected 1

What it means

Lookup guard in Designate nameToID: multiple record-sets share the queried name, but exactly one is required to unambiguously resolve the name to a record-set ID. Designate's API returned an ambiguous result.
