Changing Layer Opacity produces visible color gradient steps

I created a layer filled with black, above the original image layer, and then changed the opacity of the black layer, so it would darken the original image. I have to do this because its a mask created from a selection.

Works like I wanted BUT produces a visible gradient color steps which are not wanted on my final exported jpg. See attachment and you will understand what I'm talking about.

Please help me to fix it.

Is your XCF (or a representative cropped part of it) available somewhere?
