If I understand well you're using Woo plugin...(Woo is not compatible with Ali non-woo plugin)...Woo Pluign does NOT generate orders, it is WoCommerce who do that..Download FREE YITH WooCommerce PDF Invoice and Shipping List....it will add 2 icons to every order : WooCommerce -> orders
As far as I know, Woo does it not so good as suppose to yet there's no alternative to that on Ali. I've its issues bypassed by editing their basic invoice template with this tool ds11.pdffiller.com it's a paid one, apparently, yet I used it only once on free trial to edit the pdf and then upload it to Woo. There are some formatting issues are still appearing nevertheless, but it's a way better now
