Upgraded FW (6.2), Having Issues Calibrating pH Probes

[regala]

Hoping someone could provide some insight.

I upgraded my Profilux 3EX to 6.2 FW. I then had to recalibrate my pH probes. My first pH is for the main tank, using 7 pH to 9pH calibration. The second is for inside of my GEO Calcium Reactor, using 4 pH to 7 pH calibration.

Initially, I had issues configuring either one and the values stuck at 10.5 pH. After multiple attempts, I was able to configure the first probe and its reading was correct. Then, I configured the second probe and its reading was correct. However, it seems that configuring the second probe affected the readings for the first probe as it declined all the way to 3 pH and stuck there. So I decided to reboot the Profilux and now both probes are reading 3 pH.

Both probes are fairly new.

Any insight would be greatly appreciated as its been a frustrating day dealing with this.
