Apex and two pH probes...

So I put in my calcium reactor and got it all running, and at the time I only had one pH probe hooked up, the one that I put in the reactor itself. After I got it all tuned and happy using my Apex to control it all, I added the second pH probe to monitor the tank pH. Since then I cannot get the feed pump or solenoid outlet controls to work on my Apex. IE I have it setup to turn the feed pump on if the pH in the reactor is between x and x and turn the c02 off, then the reverse if the pH is between x and x in the reactor etc etc.

My display shows both the pH probes and in the order I would expect them in. I suspect that for some reason the way I configured the outlets for the feed pump and solenoid are reading the tank pH and not the reactor pH. I do not know what else it could be, but this makes no sense either, the prob name I set is pH, not pH2.

Any ideas?
