I should get:
1 SPM with 1 ORDER
1 SPM with 2 ORDER
1 SPM with 1 ORDER

But i only get the last SPM and ORDER (hemoglobina)

Im parsing like this:
PipeParser parser = new PipeParser(); IMessage hl7Message = parser.Parse(data);

Then converting it to XML.
DefaultXMLParser xmlParser = new DefaultXMLParser(); string xmlAsString = xmlParser.EncodeDocument(hl7Message).InnerXml;

Im doing something wrong or there is a bug in the api ?

Thanks in advance
