On the product page, in the Product reviews element, your rating option is in the form of a selection feed, while in the frontend it is in the form of stars.
Are you perhaps using the “Product tabs” element on the same page? You can’t add both at the same time as that causes some conflict in the WooCommerce JavaScript file which we can’t control. That’s why we’ve added the notice:
Hi @charaf, I do not use the product tabs element. I even removed all existing elements and used only two elements, Product gallery and Product reviews, but still the problem was not solved.
Oh yeah, you’re right there’s some inconsistency as sometimes when I refresh the styling gets messed up. This seems to be happening only in the builder on my end and is likely because some WooCommerce script is not being loaded appropriately. I’ve added this to our internal bug tracker.
