Hi again,
The problem is still persisting in build 563. Very strange!
I can save presets using the Sony Color Curves. But the Sony Color Corrector and Levels do crazy things when I try to apply a saved preset.
Levels jumps to max values all the way across (1.0, 1.0, 1.0, 1.0, 5.0),
And the Color Corrector jumps to Saturation 3,0, Gamma 2.0, Gain 2.0, and Offset -254, with the Highs pulled all the way over to 3 o’clock (blue/violet).
I am completely stumped! I’ve emailed support and will report back if they have an answer for me, but until then it looks like color curves will be my friend.
