Cause: The user enters the same option multiple times with different values (by a mistake). Pcs omits all earlier values and uses the last value. Consequence: The user is not notified that entered ambiguous option value. The content of cib can be different than what the user wanted. Fix: Pcs requires a unambiguous option value. Result: The user cannot successfully enter unambiguous option value.
