I'm in Aff Photo (via AffPub) on an iMac Pro using OS 13+. The layer object I am editing is unlocked (as well as all of the layers "above" it), my all CYMK sliders in my Colour palette are all at zero (thus not reflecting the colour of the object) and moving them does nothing on my tif. Then I just noticed a "lock" icon beside my CYMK option in the palette. Is this the problem, and if so, how do I unlock it. I've tried the usual unlock option. What is this "lock" used for? I would imagine that it locks the sliders. See the snap below.
