Add-Ons showing up but not being added to cart

I have products using the global add-ons as well as product-specific add-ons, a built in WooCommerce feature. These items show up on the quickview but do not actually get added to the cart. Please help me fix this. I require this functionality in order to use this plugin!

olympiadiner.com/order-online is where I have the menu I am currently working on.
