Extra consignments created in php sample code

[Gribanov]

I'm using code sample from docs to create consignment and return consignments.
When there are more than 1 consigmnet in $yourShipments this code creates extra return consignments because generateReturnConsignments() method is called in loop and on second iteration it will handle regular consignments and 1 return consignment created on 1st iteration and so on.
Most probably generateReturnConsignments() should be called once after the loop.

// Create the collection before the loop
$consignments = new MyParcelCollection();

// Loop through your shipments, adding each to the same MyParcelCollection
foreach ($yourShipments as $yourShipment) {
    $consignment = ((ConsignmentFactory::createByCarrierId(PostNLConsignment::CARRIER_ID))
        ->setApiKey('api_key_from_backoffice')
        ->setCountry($yourShipment['cc'])
        ->setPerson($yourShipment['person'])
        ->setCompany($yourShipment['company'])
        ->setFullStreet($yourShipment['full_street_input'])
        ->setPostalCode($yourShipment['postal_code'])
        ->setCity($yourShipment['city'])
        ->setLabelDescription($yourShipment['label_description'])
    );

    // Add the consignment to the collection
    $consignments
        ->addConsignment($consignment);
}
// Generate the return consignment
// When there are no options set, the options from the parent consignment are used
$consignments
->generateReturnConsignments(
    false,
    function (
        AbstractConsignment $returnConsignment,
        AbstractConsignment $parent
    ): AbstractConsignment {
        $returnConsignment->setLabelDescription(
            'Return: ' . $parent->getLabelDescription() .
            ' This label is valid until: ' . date("d-m-Y", strtotime("+ 28 days"))
        );
        $returnConsignment->setSignature(true);

        return $returnConsignment;
    }
);
