Renaming a route id causes outline of previous route to be visible

See attached screenshot

Notice the upper right hand corner, the outline of the route is named: route2 and it has only a from -> to.

What I did was to rename the route using the properties panel. I named the route: myRoute
And as you can see I altered the route to be a content based router example.

The outline should of course show myRoute as its the route I have selected.
