Why is the order payment flag not set when using the D7 API?

Question

1C-Bitrix

I ran into a problem when creating payments for an order through D7.
Sometimes, when creating payments (there may be several payments), which fully cover the order amount, the order payment flag is not automatically set.

The code snippet is given below:

<?
$order = Sale\Order::loadByAccountNumber(1000);
$paymentCollection = $order->getPaymentCollection();

$paySystemService = PaySystem\Manager::getObjectById(1);

// цикл для каждой из импортированных оплат
foreach ($importOrderPayments as $importOrderPayment)
{
    $paymentExists = find_payment($importOrderPayment['Document']) // определяется существование оплаты: возвращается id оплаты, либо false если оплаты нет
    if ($paymentExists === false) // оплаты не существует — создаём
    {
        $payment = $paymentCollection->createItem();
        $payment->setFields([
            'PAY_SYSTEM_ID' => $paySystemService->getField("PAY_SYSTEM_ID"),
            'PAY_SYSTEM_NAME' => $paySystemService->getField("NAME"),
            'DATE_PAID' => \Bitrix\Main\Type\DateTime::createFromTimestamp($importOrderPayment['Date']),
            'SUM' => $importOrderPayment['FullPrice'],
            'PAY_VOUCHER_NUM' => $importOrderPayment['Document'],
            'PAY_VOUCHER_DATE' => \Bitrix\Main\Type\DateTime::createFromTimestamp($importOrderPayment['Date']),
            'COMMENTS' => $importOrderPayment['Comments'],
            'PAID' => 'Y',
            'COMPANY_ID' => 1,
            'UPDATED_1C' => 'Y'
        ]);
    }
    else // оплата существует - обновим
    {
        $payment = $paymentCollection->getItemById($paymentExists);
        $payment->setFieldNoDemand('SUM', $importOrderPayment['FullPrice']);
        $payment->setFields([
            'PAY_SYSTEM_ID' => $paySystemService->getField("PAY_SYSTEM_ID"),
            'PAY_SYSTEM_NAME' => $paySystemService->getField("NAME"),
            'DATE_PAID' => \Bitrix\Main\Type\DateTime::createFromTimestamp($importOrderPayment['Date']),
            'PAY_VOUCHER_NUM' => $importOrderPayment['Document'],
            'PAY_VOUCHER_DATE' => \Bitrix\Main\Type\DateTime::createFromTimestamp($importOrderPayment['Date']),
            'COMMENTS' => $importOrderPayment['Comments'],
            'PAID' => 'Y',
            'COMPANY_ID' => 1,
            'UPDATED_1C' => 'Y'
        ]);
    }
}

$order->save();
?>

I also read the Bitrix forum with a similar problem, but did not find an answer:

try this
$payment->setPaid("Y");
