Select Colors to Enhance not working the same in Pro+ update

Previously, when using Select Colors to Enhance, you could opt for Make Transparent. And then if you adjusted the Fade and/or Tolerance sliders you could see the effect. Now this only works the first time you select Make Transparent and then appears to be broken after that.

It does seem to have changed Gary:

At best it seems inconsistent.

Captured for engineering to review. Thanks.
