I think I have a but on my prestashop 1.7 (last version), I have some products with quantity equals to 1, when someone buy the last product the the order status go to "in preparation" then changes to "out of stock" and an email is sent (I can cancel that email).
The problem is that I have that item in stock, is the last one but I have it, this information is misleading my customers.
Anyone have a solution to this problem? How can I prevent the order status to go to out of stock if is the last item in stock?
