Hi Blissdates,
First of all, I’m really sorry have taken long time to reply you.
1. Please edit single product layout and remove WooCommerce notice
widget or move it to new position https://prnt.sc/w13xvL9PU3e8
2 > 4. You are using a Custom Single Product layout, which is built with WoodMart WooCommerce builder. Navigate to Layouts > Layout to edit Single product layouts to edit sections.
Further, you can read more about the Layout Builder here: https://xtemos.com/docs-topic/woodmart-woocommerce-layout-builder/
There are 3 default tabs of WooCommerce:
+ The Additional Information Tab: Shows when the Attributes are added under a Product. If the Attributes are not added then the Additional Information tab doesn’t show.
+ Description Tab: This is the main description on the product page.
+ Reviews: Used to show customers’s reviews.
