Hidden to normal state object shows hidden still, even though normal state trigger works.

It is difficult to troubleshoot without your file.  I find it easier to do what you are describing my managing the states of a single item.  In this case, create a rectangle and edit the state. The normal state would be the rectangle with an icon inserted on top. Then click the Done button. Change the initial state of the rectangle to hidden. Then control the state change of the rectangle when all buttons have been visited.
