Don't merge the layers. simply save it as is to a PNG and it will save as it looks.
Be sure to save your original as a native photoshop image too this allows you to go back and make changes later if you choose to.

You see your first image before you merged everything down? From that point you just go File>save as> then save it as Outsource.png or what ever name you choose. you need to save it all seperated as it looks in picture one.
If you are still having issues, another way to do it is
File>new choose the default as it should be your image size by default.
edit>paste. it should look just like your masked image only not masked. Then save it as a PNG.
