Hello,
Sorry for the early confusion!
You are using a Custom Single Product layout, which is built with WoodMart WooCommerce builder, Navigate to Layouts > edit the single product layout and customize the layout.
Further, you can read more about the Layout Builder here: https://xtemos.com/docs-topic/woodmart-woocommerce-layout-builder/
Navigate to Elementor > Settings > General > Post types Check the option products: https://ibb.co/BTXTTkm then you will be able to edit the product with Elementor.
Best Regards,
