black background problem behind PORTRAIT

[Parzival]

I'm working on Warcraft 1.31. After using call

BlzFrameSetAllPoints(BlzGetOriginFrame(ORIGIN_FRAME_WORLD_FRAME,0),BlzGetOriginFrame(ORIGIN_FRAME_GAME_UI,0))

to remove Humanuitile05 and Humanuitile06. Then the problem of black background behind PORTRAIT is see-through. Is there any way to restore the black background behind PORTRAIT?. Thanks everyone in advance
