I wanted to see how the different layout options effected the route view, so I selected Radial and the view changed and a check appeared next to Radial in the menu. Then I selected Spring and the view changed again and a check appeared next to Spring as well as Radial. Then I tried to unselect Radial, but the check would not go away. I cannot be sure if I'm looking at a combination of Radial and Spring, or just Spring, or just Radial.
