The chlorine smell is probably coming from the high CC reading. Continue to keep it at shock level until the CC level drops to 0.5 or below. Did you run the pH test before or after you added a large dose of bleach? If it was done after, it is most likely inaccurate. If it was before, then it is too high and you'll need to lower it some with muriatic acid. Start with a cup or so added slowly in front of a return jet being careful not to spill or splash it and staying upwind of the fumes. Also a good idea to wear protective glasses. It is nasty stuff. Wait several hours, retest and redose until you get the pH somewhere between 7.2-7.8.
