Structured Data Different Page Type

[ChrisRoark]

Backdrop: I have a review website, and I have marked all review pages as "Review" on structured data with "itemReviewed {@type Product}". The issue is that my theme vendor adds by default a "Product" Structured data on each review page.

Both product and review have almost the same data (which is retrieved from the review body).

Does having two structured data for review and product have an effect on my website?

i think this is the answer you are looking for:

Refer clearly to a specific product or service by nesting the review within the markup of another schema.org type, such as schema.org/Book or schema.org/LocalBusiness, or by using a schema.org type as a value for the itemReviewed property.
