As the title says, I can't invert the default White mask when using Fill light / Clarity Adjustment Layer. It changes color but this has no effect on the photo. I.e. changing from white mask to black mask doesn't revert back to pre-adjustment state, and painting on the mask has no impact.
OTOH, if I just duplicate the layer, run Fill light /Clarity command, and then add mask manually, it works as it should (except, of course, that it's not an adjustment layer anymore).
Is it a bug ?
