Can't run rule actions in Button 5.0

I am trying to use a button to run actions from a Rule 4.1 rule. When I choose "Run Rule Actions" the next dropdown has nothing in it. In other words, when I click "Click to set" there is nothing else there. I am guessing this is a bug. Am I missing something?

This doesn't work yet. It's on my list to fix...

That's sorta what I figured. Just wanted to make sure someone was aware of it. Thanks for all your work. You guys are great.
