Add to cart button not available for zero available quantity products

I have multiple items available on website. I used to be able to order the items even they are out of stock, but for some reason the “Add to Cart” button no longer shows up under the item.
I can confirm I have a line for that item in the price list and price is shown in the website.

I need to be able to order products even if their stock level is zero. We then take this as production order to build those products.

Can someone please shed a light on how to fix the problem?
