Sprite Manager 2 Question May not be related

Anyone have an issue when you import a sprite sheet and when you load it on to a material, for some reason you get a white line that goes down? between the sprites? not all of them, sometimes it depends. I had a sheet of just 8 and it had 3 lines, a sheet of 6 gave me 1 line. Not sure what's causing this.

Just wanna know if anyone else is having this problem.
