Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
I have checked it and it seems it is due to you have the Product Schema duplicated (you can check with this tool you have two Product schemas in that page: https://search.google.com/structured-data/testing-tool).
That causes that you have one (the Rank Math one) added with the right information and another one (added by some plugin) with wrong information.
I would recommend you to follow this guide to try to find the plugin adding the other Product schema and disable its schema to avoid this issue: https://rankmath.com/kb/check-plugin-conflicts/
Please let us know if you find the culprit.
Only the site admin would know and your users won’t be affected by this troubleshooting.
Looking forward to helping you.

Thank you for your support. Now I made a change. Can you check again?
Hello,
The webpage schema is not genarated by Rank math.
The aggregateRating and review fields are taken from your actual product reviews that your buyers/customers leave on your products.
If you don’t have any reviews yet, that is going to show up as a warning in the schema testing tool. That’s because Google will actually look for those fields.
Please acquire some reviews and ratings to get rid of the aggregateRating
and review
warnings.
For the GTIN, ISBN, MPN issue, you can fix it by adding that to your products using the custom product attribute feature in WooCommere or you can use this plugin: https://wordpress.org/plugins/product-gtin-ean-upc-isbn-for-woocommerce/
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
