WSDL Not Generating Complete Requests

Hi,

I am importing Salesforce Enterprise WSDL in Postman and generating requests, but the request generated by Postman does not seem to be complete. When I generate the request using SOAPUi or Wizdler (Chrome Extension) there are a lot more extra information in the request. Please refer to the uploaded screenshot.

On the left hand side, I have request generated by Postman and on right hand side I have request generated by SOAPUi

As you can see, the SOAP Header is completely missing in the request generated by Postman.

What am I missing here?

It would help a lot to see the WSDL which was used to generate these messages.

Indeed, the header seems to be missing but at the same time it looks to me that Postman and SoapUI have used different SOAP versions.
