The direct answer

A shared application shell may deliver a generic title and later replace it. Different retrieval tools can therefore report different titles without either observation being fabricated.

A practical check

Compare the initial response and rendered title at the same URL and time. Identify which system owns each version.

Choosing the next step

Make important metadata delivery dependable and document the rendering difference. Do not diagnose a universal search failure from one source-only observation.
