Cannot exit Multi-Factor Authentication Security Password questions screen

Hi,

When I browse to Multi-factor Authentication > Question Settings > Edit Questions ... the screen pops up and shows the list administrator defined questions. However, I cannot close this screen once it has popped up. Even if I make a change to one of the questions and click save, I still cannot close the screen.
