The direct answer

The same identifier can intentionally refer to the same entity. It becomes a problem when conflicting businesses or locations claim that identifier.

A practical check

Compare every occurrence of the identifier and the facts attached to it. Distinguish repeated consistent references from contradictory entity definitions.

Choosing the next step

Assign distinct stable identifiers where entities are genuinely different. Retest the full page graph so fixing an ID does not break its references elsewhere.
