Waveform changes not reflected in Multitrack

Hi Friends,

     I went into the waveform, and took out all of the breath noises using 'noise reduction / noise print'.  Worked like a charm.  When I go back into my multitrack, however, the breath noises are still there.  I even inserted the waveform into a new multitrack session, but the breath noises are still there.  What is happening here?

Thanks!

Brad
