Hello,
I saw the screenshot you attached. The tabs are controlled by WooCommerce and our theme
doesn’t influence them. The only tab you can edit is the shipping and delivery tab as I mentioned in my previous reply.
I have visited your website. The shipping tab doesn’t seem to be there by default. Please make sure that you haven’t used a custom tab for the products from the edit product.
If you are still unable to find it then provide admin panel login details of the website to check it myself and help you out accordingly.
Best Regards.
