Yes, we meant the visual composer element. The simple page does not show the products by default. Very likely you set the shop page as the home page, shop page displays all the products and there is no setting to show products from the specific category only. You can change the sorting order to show the recent products first (Appearance > Customize > WooCommerce > Product Catalog > Default product sorting).
Maybe it’s possible to show products based on category there via additional customization. Submit customization request here because support does not include customization service.
