Sales order - shipment date auto-update

Here is the situation:

I have a SO that I have attached a delivery mode. This mode of delivery is associated with the customer’s address from the transports form (Inventory management → Setup → Distribution → Transportation), i.e. it has setup a delivery of two days.

I have another mode of delivery setup with the customer’s address, but it has a delivery of 5 days.

When I change the mode of delivery from the SO, I get properly from the form Simulate Deliver Dates (SO → Delivery tab → Simulate Deliver Dates button). However, when I set new delivery date (via Transfer to Requested date button), the requested ship date and requested receipt date are the same, i.e. it’s like the system does not consider the setup transport days from the delivery mode. Any idea if I am missing a setup parameter?
