Made a pixel art template, moved the top portion down to make a shorter version, shorter version still displays taller version behind it?

as per the images. I made the taller white version, then used Ctrl + Alt + drag to move the top section down to shrink the body and make the whole model a little shorter. After recolouring, I exported the shorter version to find the tall version still visible in the background.

Did you copy the layer and work on the copy?
