Why can't I change a variable of my widget?

For some reason I cannot edit my variables in my widget, I want to change the visibility of my “RobotsBuildButton”(see image below) for some reason I cannot change the default value. The weirdest thing is when I click the “Editable box” nothing happens, it stays editable. My own variables in the widget are working correctly.
