Hi! Solution is to load them properly ;-) All frames are of same size and character is centered in same point. Right now unpacked «Attack_1» and tested in editor.construct.net as a sprite. Works as expected.
I have some thoughts that you are trying different Row X Col quantity or your game engine has some kind of euristhics/clip transparent area option enabled. Try other software to play the spritesheet. At least the free version of editor.construct.net as a fast prototyping and testing tool
