Hi,
The PayPal API only allows one address to be added to the transaction.
In the settings of the PayPal payment method, you have a setting to select which one.
Regarding the shipping address not included in the email notification, it's possible if there is no shipping method attached to the order. Maybe that's why ?
The stock can change either upon order creation or upon order confirmation. This is dictacted by the "Update the product stock on confirmed status" setting of the HikaShop configuration.
So if that setting is deactivated, regardless of whether the payment is made or not for an order, the stock will be decreased.
Regarding the orders not being confirmed, this means that the PayPal payment plugin is not receiving the payment notifications from PayPal. It could be an issue with how you configured your payment method, or something else on the server.
We have a documentation you can follow on that:

If you deactivate the "out of stock" display setting of your menu items/modules, out of stock products won't appear on the listings of your website. Still the product pages will be accessible if accessed directly (like if someone click on a link to it from a search on google, which is a good thing for your SEO), but the customers won't be able to purchase the product in that case.
Now if you really want to unpublish out of stock products, you can run a mass action every minute to change the product_published to 0 if both the product_published is 1 and the product_quantity is 0.
