The key logic is that in a two-step delivery, the first step represents picking products from the warehouse into a staging or transfer location (internal movement), and the second step is the final delivery from that staging location to the customer. When printing the picking operation PDF for the delivery step, Odoo uses the "destination location" to determine the address shown in the warehouse address section. Since the final destination of the goods at that stage is the customer location, the system shows the customer’s name and address there.

In simple terms, for the “pickup” step, the warehouse’s physical address is shown, but for the “delivery” step (the move from the intermediate location to the customer), the system displays the customer’s address because the picking is directed there. This is why the customer name appears in the warehouse address section on the picking operation PDF—it indicates the current destination location of the stock move, aligning the document to the flow of goods rather than strictly the warehouse origin.
