I am having trouble showing the Woo Commerce "Add To Cart" button when I enable Multistep. It works fine when I don't have it active. I checked the settings and checked the error logs. I don't get any errors. It just keeps saying, "This product is currently out of stock and unavailable." 

Here is the list of plugins am using: 

• Multistep Product Configurator for WooCommerce version 1.2.4
• WooCommerce version 5.2.2
• Fancy Product Designer Version 4.6.7 
• Divi Version 4.9.4
