Photoshop :: Image Exported - Place On Image (Like Watermark) Misaligned After Save

I have an action in which it will place an image onto an image like a watermark, when i place the image, it is not center by center so i drag it or use keyboard arrows to center and then press enter, then i saw its on the center, but when i save it, the saved image is not on the center, how was that?
 
you can see that the right side of border it is not centered because the left side border is thicker than right side, here is the part of the action
 
you can see that i move the image after i place it because its not on the center so adjusting it makes it at the center but the Translate part is not equal.
