is LoadUI(pro) Bug !

Hi,
I'm evaluating products SoapUI NG (pro) and LoadUI NG (pro) under Ready! API 1.2.2 by following below references -

http://readyapi.smartbear.com/loadui_ng/getting_started/creating_soapui_project
http://readyapi.smartbear.com/loadui_ng/getting_started/creating_load_test
http://readyapi.smartbear.com/loadui_ng/getting_started/running_load_test

I have a datasource (excel file with a list (say 5k) of order numbers) and using a data-source loop I'm calling a webservice which prints the orderID passed to it in runtime in server log.
While I execute the test case (Datasource,webserviceCall,Datasource loop) directly in SoapUI NG (pro) tab (same as portrayed in above urls), I see the order numbers are printed correctly in server log.

However, while I create the 'New LoadUITest' by following above urls from this SoapUI NG (pro) test case and execute it, I find only '?' getting printed in server log (irrespective of values I set for Load Type, Arriving Users, Time period etc)

Can someone share whether you have face this issue ?
