Godot 3.5 Altering PNG for unknown reason [closed]

For some reason, a grey line has been added to a sprite that was not present in the .PNG I used. The grey line shows up in both the editor and inspector, despite the fact it is not present in the .PNG itself. I have tried with and without, both filtering and GPU pixel snap. changing the sprite's size to be bigger or smaller also changes the size of that line by the same amount. I just the image to be the same as the PNG is outside of Godot.
