Right now, the default behavior when you click the X on the "advanced" tab is to turn two toggles to ON. This causes the button to become blue.
It's a little awkward because the user clicks the X button, and the button doesn't change color back to grey. This makes it look like nothing happened. This behavior does not match that of the other filter buttons.
Maybe add a special case for the Advanced (and season) buttons to make them grey when the default filtering is applied?
