The diagram name indicates an intersection. The diagram type is not an intersection.
A new feature of the program calculates the most common name for an intersection when aliases are used. It calls this the “favorite” name. Versions of the program with this problem will display the “favorite” intersection name, even when presenting a corridor, milepost, all data, or other diagram.
Note that the window title will still be correct. It is just the printed annotation that is incorrect.
Upgrade to v6.511 or newer.
Workaround: Click on the annotation and re-type the appropriate name.
