The two triggers: "Change state to Hover" and "Change state to Selected" are the problem. All the built-in states (like Hover and Selected) have their own superpowers. That means if an object has a Hover state, it will automatically change to Hover when hovered over, and back when hovered off. But if you create a trigger that says "Change state to Hover..." you run a huge risk of creating a conflict with the built-in state. If that happens, the results are seldom pretty. The same with Selected. When clicked, it turns to Selected, and when clicked again it changes back to Normal. You need to delete those superfluous triggers, or change the names of the states.
