Control Points No Longer Working As They Used To

I just installed the latest “fix” to get Viveza and Silver Efex working on my Mac with PS 2021. Control Points no longer seem to work as they used to. I add a control point for a local adjustment in both programs, and the control point adjusts the entire image. I add another control point to remove the previous adjustment from another area, and it too adjusts the entire image and seems to be in sync with the previous control point. Am I missing something? The program no longer works as it used to.

In the new Viveza and Silver Efex Pro 3, control points have adjustable selectivity (color and luminance) which will affect how much of the image is included in the mask. That has more of an effect than the radius of the control point, which is feathered and doesn’t have strict boundaries.
