Problem with ControlNets

I'm following the ControlNets usage description, but nothing appears automatically in the circled line, unlike what's stated on the page: https://github.com/easydiffusion/easydiffusion/wiki/ControlNet And I can't select anything; I've circled it in red to show that the menu is empty. And when I try to generate, I get the message in the second screenshot. It says it'll take a while during the first image, since it'll download about 1.3 GB of models for the Canny Control Network. But it doesn't try to download anything, it just displays the message in the screenshot. How to make this feature work?
