Product's stock reduces on Add to cart

[DavidSanek]

Hello,
when a customer adds a product to the cart, the product's stock reduces. I want the product's stock quantity to stay the same. Only after order completion I would like the stock to be reduced. Is there any way how to get this behavior? Couldn't find it in the PrestaShop's settings.

Current behavior (tested at official PrestaShop demo):
1. Product A has quantity of 10
2. Customer B adds Product A to the cart
3. Product A has now quantity of 9, even though the Customer B did not complete the order

Wanted behavior:
1. Product A has quantity of 10
2. Customer B adds Product A to the cart
3. Product A has still quantity of 10. After the Customer B completes the order, Product A's quantity will be reduced to 9.

Thank you.
