Sims 4 cc hair texture not showing

So i've been trying to edit custom alpha hair for my sim. When something is right, then the other thing is wrong. Now when i have the right color, the texture is missing. I recolored the texture file with gimp and nothing else. I use blender for the editing.Why the texture isn't showing in the game after the recoloring? I didn't change anything else.

The texture is only visible in those edits where the color isn't right.

I am also wondering that do i have merge the layers after im done with the edit? The hair looks very thin in the game so i thought that the other layers didn't show up.
