Hello! At the moment, there isn’t a built-in setting in the plugin to disable the “Add all to cart” button. It might be possible to hide it using Custom CSS by targeting the specific button only.
Also, the second cart button might be needed because we use a 2-step cart flow in WooCommerce. First we collect the selected product IDs + quantities on the results page, then Proceed to Cart/Checkout sends that list to WooCommerce to add everything to the cart. This is required by how WooCommerce/WordPress handles cart actions.
If you have additional questions, you can also reach us directly at team@revenuehunt.com so we can further check it specifically for your store.
