Hello, Namaste,
Thank you for your reply.
[products] is the default WooCommerce shortcode https://woocommerce.com/document/woocommerce-shortcodes/
Please check how it works when the default WooCommerce theme – Storefront is activated. If there is a bug (an issue with product output), then this is an issue with the products (perhaps some products are only indicated to be shown on the shop/search, which is why they are not being outputted on a custom page).
Kind Regards,
8theme team
