Im having trouble with Audio Snap and quantizing audio

So here is what happened....
 
I wrote a Orchestral piece and had a Electric Guitar player play a part.
His timing was a little off, I quantized his audio.  It made the guitar part have a cool stutter and play in time.
When i play back audio, I hear the cool stuttering.
When i mix down, freeze, bounce to clips, anything to output the new audio...no stutter and the original slightly off is back.  The quantizing is not there.
 
Play it back in the session, it is there.
 
I've tried a bunch of ways to mix down. 64bit on and off,  fast bounce, no fast bounce...Ive tried the R!(enable read) toggled both ways.
 
Am I missing something?
 
THANKS in advance!
