Alpha Mask and Gimp Gone Crazy

Started having crazy behavior with my Twilight alpha mask and Gimp. Going through the proper procedure , open Gimp with my Twilight render image , right click add alpha mask to image. Do a copy and paste with Twilight alpha mask and anchor the floating layer. Problem is I'm getting a partially transparent final image. When I import the image to use in the masked area it ghosts through the whole image. Any ideas whats happening ? Posting an example image....

Adjust alpha mask contrast in Twilight or in Gimp

Agree with Alvydas, when you save your Alpha Mask Rendering from Twilight Render be SURE to have Tone Mapping and all post Processing set to NONE.
