Either "Offers", "Review" or "AggregateRating" should be specified

I've just converted my website to a WordPress WooCommerce platform. https://swordsofhonor.com.

Either "Offers", "Review" or "AggregateRating" should be specified

on this page – https://swordsofhonor.com/product-category/die-hobby-stone/
This is a category of & # 039; Page with 2 articles. I have no idea what the error message means or how you can fix it.
