I think this is a bug. It at least seems strange.
I have a button that I want to show when a user is logged in and not when they are not. I set the conditional statement to be: Current User is Logged in.
Then I set the property to change to be: This element is visible. The box is checked.
When I test it, it doesn’t work: the button is always visible whether the user is logged in or not.
I’ve gotten around this by doing the inverse which works fine: When user is NOT logged in then do NOT make this element visible.
