I use Odoo 14 and I have a configuration problem when receiving materials. 

When I create the purchase order manually, two orders are created, one moving from the supplier to the receipt and from the receipt to the stock, only keeping the materials corresponding to that purchase order. When I use the replenishment, the second order (from the receipt to the stock) is created by unifying the products from all open purchase orders. How do I fix this so that it looks the same when I create manually?
