Sorry for being toxic but your skin is broken.
I know you used the default skin as template. Also the problem is you skinned only normal size files (the files without the "@2x") and keep the "@2x" files as is. So your skin is literally the default skin on large screens (he works on small screens btw).
Do you know what are these "@2x" images? They are images but 2 times bigger. They are used for large screens (like 1920x1080 screens).
To fix this you can just remove all "@2x" files. This should remove the defaults elements on all screens.
Also, I don't recommand to do that. When you make a skin,
always skin @2x elements first because you can't make @2x images by scale by 2x the normal sized files: the quality is too bad. You have to make the @2x sprites firsts and after create a copy, scale them by 0.5 and remove the "@2x" (
this program do very well the process btw): so your skin will be in good quality for all screen sizes.
I think you should restart your skin from 0. You can't do anything with just the normal size files.
Sorry for being toxic.
