Soap UI 2.0.2 to SOAP UI 2.5.1 PRO - Glitch or something...

I had found something new to made my old soap 2.0.2 ui request work in the new version.

That line had been add in the new version at the end of the request:

     

When I remove it, my request work fine with his expected result.

When I keep it, I get :


   
     
         soap:Server
         Index: 3, Size: 3
     
   



So, what is wrong here?
Does that line is important? 
Why this is in SOAP Ui PRO and wasn't there when I generated my test with SOAP UI 2.0.2? 
Can I remove that line...  per say, switch some config on/off and reload my project?
