The 4-th curve (alpha channel) in the color adjustment layer don't work as expected. It only affected the overall transparency of the layer, regardless of underlying brightness. Reproducible: Always
More precisely, only the last point of 4-th curve affected the transparency.
I don't see any problems. It works as in Gimp. Can you show a screenshot of the issue? My screenshot: http://i.imgur.com/c1e9hye.jpg

No problem -- it's always good to check!
