Sorry in advance if this is just simple user error - but I understood from the tutorials that labels that are red indicate an error.  I cannot create any models without an error, so I reverted to simply trying to add a tied anchor to the sample model.  I tied it to the Performance anchor, then tried to replicate the 1-1 mapping as for the Event anchor.  I named it Ev2, named the role names identically to Event, and cannot see any difference between the Event and my Ev2 - yet Ev2 is still in red.  What am I doing wrong.
