Hello. How to correctly set the order payment flag in Bitrix via api? I use the following construction:

use Bitrix\Sale\Order;

$order = \Bitrix\Sale\Order::load(1478);

$paymentCollection = $order->getPaymentCollection();
foreach ($paymentCollection as $payment) {
    if (!$payment->isPaid()) {
        $payment->setPaid("Y");
    }
}

$order->setField("STATUS_ID", "F"); // статус заказа - выполнен
$order->refreshData();
$order->save(); // сохранить заказ

In this case, the paid amount is set in full, but the payment status is not paid:
