Correcting Value

[nightape]

I have had it go both ways - sometimes the correction is less, sometimes more. I no longer click to let them correct the value. I un tick shows to add up to the amount in red manually myself.

Was just on the credits transfer request page and as normal it was highlighted in red about so many credits being unavailable and to click here to correct the value. I did that and one of my DirectCam credits to my account has changed and now reads - Credit DirectCam - xxxxxx (Was 1.83) 1.72. Why has the amount changed? I've never had this before when I've corrected the value
