soapUI 4.0 request missing content

I downloaded soapUI 4.0 windows 32 bit installer. Previously I had soap UI 2.5.
I loaded my project using my wsdl but my requests are missing some elements. Example:
Example:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ws="http://ws.nsq.sciquest.com/">
<soapenv:Header/>
<soapenv:Body>
<ws:executeCreateRequisition/>
</soapenv:Body>
</soapenv:Envelope>

When I do the same wsdl in soapUI2.5, I get. Please note the tags with ?.

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ws="http://ws.nsq.sciquest.com/">
<soapenv:Header/>
<soapenv:Body>
<ws:executeViewRequisition>
<!--Optional:-->
<arg0>
<!--Optional:-->
<requisitionNumber>?</requisitionNumber>
<!--Optional:-->
<userIdentifier>?</userIdentifier>
</arg0>
</ws:executeViewRequisition>
</soapenv:Body>
</soapenv:Envelope>

Why am I not seeing the elements in soapUI 4.0? Thanks in advance.
