My Finish button is missing on all of my flows.  

Yes, I have checked the Screen settings and No, I am not hiding the Finish button.  

When I run the flow, all I see are the "Next" and "Pause" buttons, even if the flow has only one screen.

I have searched all over and I have not found a single person who has had the same problem.  I'm stumped as to what the problem could be.  Has anyone else encountered this and found a solution?
