This is almost always a crawl-to-index lag, not a schema parsing issue. Claude's training data snapshot is older than its live crawl, so it's pulling answers from the newer crawl but attributing to whatever URL was in the training corpus. Add explicit schema.org/version markup + ensure dateModified is ISO 8601 on every update, but the real fix is submitting your updated URLs to Anthropic's crawl request form if one exists—otherwise, you're waiting for the next major model retrain.
