I've seen something like this myself. Unfortunately I don't recall exactly what the solution was. From memory, it may have been competing point controls, or it might have been a problem of multiple templates dropped in that corridor, which means your superelevation points may take different names.
Consider disabling all point controls other than the superelevation controls, to see if that does anything for you.
Also, select one of the superelevation points that the corridor generates (the right edge of pavement, for example, if that's appropriate for you) to confirm that the name of that element is represented in the superelevation point controls.
