Last Polled Value of a Performance Monitor

Last Polled Value of a Performance Monitor

Hi, I am testing OpManager V12 and I'm having some trouble with the "Last Polled Value of a Performance Monitor" widget, if I test the monitor gives me the correct value, however when I add the widget to any dashboard and select the monitor I ant to display it shows no data at all. Any idea what might be?

Thanks in advance for your responses
