Decal not placed on left, right and back of the head part

Hello DevForum. I have textures to add on head of a character but for some reason the decals aren’t pasting on Right, Left and Back of the head (Haven’t check for top and bottom parts).

If I remember correctly (but, I am probably wrong) you can add decals to other sides of heads.

But, whenever I try to paste the decal on other sides it just doesn’t work. I checked is the decal moderated and it’s not and tested it on other part (classic block).

Just if there is confusion I am talking about normal head (shown below)

Any help is welcome!!!

Try copy-pasting the decals with the face set for each side.

Tried it now. Unfortunately, it’s not working.
