Rule Machine broken edit flow

Edited
I'm trying to setup a conditional rule based on last event. When I try to setup the condition based on the last event for temperature, I don't get a field to allow selecting criteria or a button to move on to the next step. If I create the condition using Any Attribute, I am able to successfully complete the rule. I can then go back into the condition and switch it from Any Attribute to Temperature and the logic seems to stick.
