How do I use the debugger?

I'm trying to debug a function I wrote. According to the documentation it says that when the game stops on a debugger, the Resume and Step buttons will be replaced with Continue and Next. That just... Doesn't happen. I have no idea what I'm doing wrong, I followed the documentation. Is there some missing step you need to do in order to get it to work?...

I just tried it and it seemed to work fine. The "step" and "continue" buttons work as expected. What are you seeing?

Just... Nothing. I see the Step and Resume buttons, but nothing happens. I can click step a million times and it just won't move to the next step despite being right there.
