Hello,
1) We have options to enable/disable elements and change the order of the elements in the Quick View (Theme Options > WooCommerce > Shop elements > Quick view). We don’t have the builder for the Quick view like for the single product.
2) Products are out of stock on your site http://prntscr.com/u2t0z1
Please, read the WooCommerce documentation and change the stock status of your products to be able to add them to cart
