Why can't I see my Rooms?

I have applied a filter where Category Name is Rooms, and I can see the rooms in the Grid, but I do not see any geometry in the Viewer.

To make them visible:

1. Click on the Visibility Settings link.

2. Click on the ignored categories.

3. Uncheck Rooms and update the Settings.

4. Modify the newly created rule to SHOW ONLY Rooms.
