We had a lot of inquries about missing icons in product type column WooCommerce product list. Users were asking why icons vanished in WooCommerce product list and how can they get it back. From WooCommerce 3.4.0 update, WooCommerce developers removed that column in product list (as a result of users’ feedback).

There is way to restore it back using this plugin https://wordpress.org/plugins/woocommerce-product-type-column/ so in case you are too missing this feature, download and activate this plugin and icons will be back in product list.
