Wordpress and WooCommerce + Tutor LMS plugin help

Looking to fix/change a Wordpress Plugin to allow us to use a Woocommerce feature. The Wordpress theme we have is called Edumall, and the plugins are Tutor LMS and Woocommerce. All work fine already and we can add products to cart and checkout, however for some individual products, we want to use the Woocommerce "External/Affiliate product" option. When we apply this under the product in woocommerce, and add new button text and a external URL link, the button text changes, however the action of opening Link does not work, it still just adds the product to cart. I assume we need some custom code added somewhere for this to work, as the Theme must be set to only use the single product and not external product option in Woocommerce. Need this to be resolved in next few hours.
