Looks like you are using the “Comments” elements. Which is intended to be used for single blog posts, instead of products.
If you use the “Product Tabs” element instead, it should contain the “Reviews” tab. Can you try that and let me know if it’s working for you?
Can “Reviews” be made into “Product Reviews.” which can be directly called elements like “Product Title” and “Porduct Content”. It is not necessary to use it with “Product Tabs”! Because the layout style of this tabs is too rigid, the design is too old and not modern enough.
Just to confirm: You suggest having a dedicated “Product Reviews” element, so you can style it in any way you want?
