Role selection buttons have poor affordances

Summary: We display Role(s) with cutesy-poo buttons that look nice. But they lack any affordances telling you that you can change them.
At the least, we should drop back to plain old Selection drop-downs. But see if we can do something nicer using Bootstrap buttons with drop-down arrows and context menus.
