Incorrect values getting passed

I have a .Net WCF service which I am testing with SoapUI version4.6.2. All is working but I have an issue that I just cannot get around at the moment.

I am using a password digest which adds a nonce and a created date. The passwordType is set to PasswordDigest.

So, when I make the call, these values are populated into the Soap Request as below.

<soapenv:Header>
        <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"
                       xmlns:wssu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
            <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" 
                                   xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
                  <wsse:UsernameToken wsu:Id="UsernameToken-38"><wsse:Username>XXXXXXXXXXX</wsse:Username>
                         <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">0OLlyLiaAjG+APSRFyHkWl8b5BQ=</wsse:Password>
                          <wsse:Nonce EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary">wmI0VZSTAmrJ0ELQa7ybcQ==</wsse:Nonce>
                         <wsu:Created>2013-12-09T12:43:13.895Z</wsu:Created>
                  </wsse:UsernameToken>
             </wsse:Security>  
      <urn:ESBMetaData>            <urn:OriginalServiceCallerID>xxxxxxxxxxxxxxxxxxxx</urn:OriginalServiceCallerID>
        </urn:ESBMetaData>
        <urn1:ESBContext soapenv:mustUnderstand="1">
            <urn1:BusinessContextType>xxxxxxxxxxxxxxxxxxxxxxxxxxxxx</urn1:BusinessContextType>
            <urn1:BusinessContextInstanceId>uuid:7dc57353-9069-442d-8b69-163f676dd3e3</urn1:BusinessContextInstanceId>
            <urn1:ServiceRequestId>uuid:7dc57353-9069-442d-8b69-163f676dd3e3</urn1:ServiceRequestId>
        </urn1:ESBContext>
    </soapenv:Header>

But the values for the password, nonce and created date from with in the .Net WCF service are as follows:

Username := XXXXXXXXXXXXXXXXXXXX
Password := drke/Qbzob5IY7KzmCBeb6q09ho=
Nonce    := oZiTJpbiVrranub4F1Sjbw==
Created  := 2013-12-09T12:43:35.320Z

The funny thing is thou, that if I call the service again, I get the following

<wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
<wsse:UsernameToken wsu:Id="UsernameToken-39"><wsse:Username>XXXXXXXXXXXXXXXXX</wsse:Username>
<wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">drke/Qbzob5IY7KzmCBeb6q09ho=</wsse:Password>
<wsse:Nonce EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary">oZiTJpbiVrranub4F1Sjbw==</wsse:Nonce>
<wsu:Created>2013-12-09T12:43:35.320Z</wsu:Created></wsse:UsernameToken></wsse:Security>  
      <urn:ESBMetaData

Which as you can see is holding the password and nonce values that the .Net WCF program thought was the original call.

Must be something simple, but cannot see it. Any help?
