" " rect lies (partially) outside of texture. Will not generate Sprite for this Slice.

So I have a PNG image that consists of each limb of the sprite I want to use and I set the sprite mode to multiple, splice it in the sprite editor, and set up bones and geometry, but when I drag the sprite sheet into the scene I get the window to save sprite animation, but only one part/limb of the sprite sheet shows up in the scene and I get the warning, "' ' rect lies (partially) outside of texture. Will not generate Sprite for this Slice." I have no idea how to fix this, please help!
