NX Mirrored Operations are Shown as out-of-date in the Operation Navigator

Several Operations are to be mirrored using Object -> Mirror .

In the Path Settings the Maintain Cut Direction and the Maintain Cut Angle are checked on to keep the tool cutting in a climb cut direction. When created why are the mirrored operations displayed as out-of-date?

If the Maintain Cut Direction and Angle options are selected when doing a mirror operation than the path will either need to be regenerated manually or the Generate Tool Path option will need to be checked on. This is necessary in order to recalculate the engage, retract and stepover moves to prevent the tool from hitting the part.
