Hello,
1) I’ve added “Shipping tab” static block on your site. Please check – http://prntscr.com/pbmlhi Additional Information is a default WC tab – https://docs.woocommerce.com/document/editing-product-data-tabs/#section-6 and should be shown automatically. Is it shown on your site if the default theme (Storefront) activated?

2) You need to install and activate WishList and Compare plugins (Appearance > Install plugins) + https://xstore.helpscoutdocs.com/article/102-wishlist
Regards
