"SHOW" not working

Hi, I'm working on a model where I hid a number of items to show a construction sequence.  My plan was to "show" the components as needed.  My problem is the items are not reappearing in the model when I "show" them.  In the screenshot below, you can see all items are resolved, and there should be 8 pcs showing.  Only 1 appears.  Not sure what I'm doing wrong.
