CST - Power Calculation on Material/Solid

I have problem checking out power calculation on material/solids in postprocessing. For example, after clicking on loss and Q in postprocessing, "Sum of surface losses", "Volume losses" are available. But I have a few solids with different materials, and supposed to see power on each solid upon clicking on Hide/Unhide All. When I clicked, nothing came up. Any possible solution to see them?
