We have a brand new look! Take a tour with us and explore the latest updates on Adobe Support Community.
You're setting the Opacity of the entire component. After switching states, double-click on the content to go into that component's state, and then change opacity.
Is this a new update? No one in my class seems to have his problem. I never needed to double-click a simple component in order to enter its state.
You don't have to double-click to go into a state for everything. For example changing a fill color does not require that. But for opacity you do. I'm not sure if this is a new change, but it's because the entire component could have its own opacity, versus the elements inside having a separate transparency.
