Why is the shipping cost not added to the payment amount for the order?

Question

1C-Bitrix

Faced a problem. There is an online store on Bitrix, which other developers worked on, when an order is placed with delivery, the delivery cost is not added to the amount of payment for the order, the amount for delivery is shown separately, only the amount for the goods is reflected in the amount payable .
For example, select the delivery service joxi.ru/8234OPeikBXyAO, then place an order and look at the order information in the admin panel joxi.ru/GrqKM46SjM832z In the amount for payment , only the cost of the goods is indicated, the cost of delivery does not fall there. With what it can be connected? Is it possible to specify an additional parameter in the settings of the checkout component? Or in the delivery service settings?
