Line at the top of the image

1. I want to fix the problem with the line at the top of the image.
   
   

2.When I upload an image it’s clean without a line. After a while, this line always appears. (I think that’s after Roblox processes the image.)

3. I’ve already tried to be where the line is, so I erased this place.
   

The strangest thing about all this is that it is formed only on the triangular signs always at the top.

I think it’s a problem with roblox compiling the image or something. I noticed the the lines are off of the sign, so I think making it a texture instead of a decal will make the image stay on the part and not go off of it.
