Photoshop 21.2: Selective colour effect not working

I want to convert an image to black and white and then bring back colour to a selected area. So I added a Black & White Adjustment layer and that gave me the black and version of my image. I then selected the Brush Tool and set my foreground colour to black. However when I begin to paint over the part of my image on which I want to bring back the colour I am not successful. I click with my mouse on part of the image and colour appears but as I try to add further brush strokes nothing happens - you can see the green circle where the brush touched but any further strokes results in nothing.

When I'm using the mouse to paint in areas of the image nothing shows (although the area is visible on the mask). But if then make the layers invisible and then bring them back I can see the painted areas. But that isn't a lot of use when I'm painting as I expected to see the "colour" areas as I paint them. The image shows the painted areas after clicking off and clicking back on the layers. 

















Does anyone have any idea what I'm doing wrong?

Hard to tell from the screen grabs. Were you using the brush tool and not some other painting/cloning tool on the mask? 

Possible to post the file?

Go to Preferences - Performance and turn off Legacy Compositing.

As I said to you on the Lightroom Queen site, Johan you are a marvel! Exactly as you suggested and now it works perfectly! I wonder how many other people have tried and given up with this without ever realising that changing this setting solves it? And I wonder that Adobe don't give a hint about it somewhere. Anyway I am eternally grateful to you. Thank you.

well, what you're seeing is a bug and the only way Adobe would know to fix is if folks report the issue like you've done here...

I think this is a lesson for Adobe. Legacy compositing is turned off by default, but if the user turned it on in a previous version (and in previous versions that was sometimes necessary), then it stays on with the update. The update should force it off, Adobe!
