States Problem

Hi All, I'm a new Storyline user and am having trouble getting object states to behave as I want them to.  I am trying to replicate a slide from the content library where the user clicks on different controls to see different layers.  When they click on a different control the previously selected one returns to normal.  In my slide, the selected control doesn't return to normal when they select a different control, but when they click on a control a second time, it does return to the normal state.  Basically I want my slide to behave the same way the one from the content library does.  I have attached the file, my slide is slide 1 and the content library one is slide 2.  Many thanks!
