Structured Data Warnings in product pages

For the website https://www.Nutrimedical.gr, which is a food supplement eshop and runs WooCommerce, some warnings are occurring for all the products in Google’s Structured tool https://search.google.com/structured-data/testing-tool, the review and the global identifier fields

https://prntscr.com/q8rg8i

For this product which is a supplement to counteract abdominal pain symptoms

https://www.nutrimedical.gr/product/actibutir-ευερ?θιστο-?ντερο/

Two warnings are coming up but both fields are normally presented in Woocommerce and in the page

Can those warnings be fixed if WP SEO Structured Data Schema is been installed?
