When you have a unit selected, then click on a resource, the resource count shows up as expected:

However, when nothing is selected, then you click on a resource, nothing shows up:

To reproduce, click on the ground so you have nothing selected. Then select a resource. Note that the resource is selected, but you get no information about it. Now select a unit, then select the resource again. Now you see information about it.
