you probably did not installed WooCommerce plugin before demo import and that's why products are missing. So if you want to get exactly same products, now you need to to remove whole data, using Wordpress Reset plugin. But please remember that this plugin removes all data, like: pages, posts, settings, etc. Your Wordpress would be again as clear as after first installation. After that, you need to install theme, all necessary plugins and then do the import once again.
