The same schema type is declared in more than one JSON-LD block

What this means

Two or more separate JSON-LD blocks on this page each declare the same @type — typically an SEO plugin and a hand-rolled snippet both emitting an Organization or a Product. Search engines have no rule for which copy wins, so any field the two blocks disagree about (a name, a logo, a price) resolves unpredictably. Types Google documents as legitimately repeatable per page — multiple breadcrumb trails, one VideoObject per video, one Review per reviewer — are excluded.

How to fix it

Keep one block per entity. Merge the duplicates into a single @graph, or disable whichever source is emitting the redundant copy, then re-test the page in the Rich Results Test.

Fix effort

This check needs review: the change can be drafted for you, but a person has to approve the wording or choose the target before it ships.
