Problem with 'Open URL'

When I select this it populates with https://KeyboardMaestro. I can not get it to change. What am I doing wrong?

Maybe what you put is not taken as a url?
Try something else like and see it works?

Oh. FYI, you can just paste your screenshot to the forum. I don't know how you did with the screenshot, we have to download it to see it. If you direct paste the screenshot to your post, it will show the screenshot.
