Button State (Disabled) not staying

Hi - I have a button, initial state normal and blue. When the button is clicked, I have two triggers 1) go to another slide, and 2) change state of the clicked button to disabled. The disabled state is white. 

When I return to this slide, the button is in its normal, blue and enabled state, but should be white and disabled. (Note that this was working for some buttons before, and now is not working for any buttons. )

I have three states for each button: normal, hover, and disabled. 

I have also experimented with the order of the triggers, which had no effect. 

Is this a bug?

Thank you for any suggestions.

- Amy
