Issues with PDF from DOCX Plug-in when word document has classification

Hi Everyone,

As part of our client's policy every document needs to be classified as public / private / confidential.  when we upload a document that has classification as "confidential" and trying to generate PDF document with the help of plug-in "PDF from DOCX"  I'm receiving the following error message : 

com.appiancorp.ps.adt.conversion.DocxToPDF - Error while executing Custom Smart Service
org.apache.poi.openxml4j.exceptions.OLE2NotOfficeXmlFileException: The supplied data appears to be in the OLE2 Format. You are calling the part of POI that deals with OOXML (Office Open XML) Documents. You need to call a different part of POI to process this data (eg HSSF instead of XSSF)
