Led light on handcent

I've set all of the notification led lights the same just different codors for different contacts. One contact does not show a notification light. All others work. This particular contact is in the private box. All settings are the same for each contact...what am I missing.? Did I possibly turn something off or switch something on this one contact?

It is probably the private box that makes the LED not blink. That makes sense since the point of the private box is privacy.
