i am expecting shipToIdentifier to be repeated only once in the target but it is coming two times along with the shipment address because the shipToIdentifier is same for both shipment address:

    <shipToIdentifier>0000320101</shipToIdentifier>
            <shipmentAddress>
                <name>Shenzhen Diwei Video Co., Ltd.U</name>
                <city>Shenzhen</city>
            </shipmentAddress>
            <shipToIdentifier>0000320101</shipToIdentifier>
            <shipmentAddress>
                <name>深圳迪威影像有限公司XXXX</name>
                <city>深圳南</city>
            </shipmentAddress>
