after selecting part of an image with selection brush tool while applying effects a ghost image is created on top of the selected image and the effects are appearing on that part only. this was happening on landscapes where a cloudy sky was selected with a tree line below as border to edit the sky a ghost image of the tree line was appearing at the centre of selection. i am attaching 2 pictures taken of the screen shot. in short i am unable to edit the selection. all edits are appearing on the ghost image created automatically. the raw file imported was taken using my nikon d7000 camera.
