Staad.pro Connect Edition Build 21.00.00.57 I cannot select a profile section from the database

I am self learning Staad and am following the first tutorial; this is the three-member portal frame with uniform load along the beam.  As I go through the tutorial, whether its building the model using the physical modeler or using the analytical modeler, when I try to assign a profile, I cannot. 

In the physical modeler, when I select the two columns to assign properties (profiles) and select the AISC W sections, the display field stays blank, i.e. no selection can be made. 

When I am in the analytical modeler, when I hit the Specification tab and the "properties - whole structure" window appears, all the selections are not active (not available for selection).

I've checked the Section Database Manager under the Configuration tab and can see all the shape file .db3 databases. I've tried to select these and to save but to no avail.  What is the problem here?
