Just an idea
If you are positioning it in the layout
but it is moving in your game
then maybe it is an animated sprite? (or you have more than one frame by mistake)
and for the last frame you are stopping on, the origin point is in a different place than in first frame?
This will cause it to move place in game.
(as you position in layout from origin point of first frame then it moves to the origin of the last frame in game)
