Bezel correction glitch?

[GabenHood]

Having this weird issue where any time I try to adjust bezel compensation in CCC it adds an extra 100 pixels (ish) to my total res. Eventually I have to revert back to my stock grouped res (4480x1080 missmatched 5:4 - 16:9 - 5:4) or revert to factory defaults and start again.

Upon trying bezel correction again after a reset it adds yet another 100 pixels to the total res. Using Win7 64bit, originally 14.6 beta but even updating to 14.7 didn't help. Anyone know a way to completely reset bezel correction values in CCC or perhaps registry?
