My skin

So I got Minecraft not too long ago, about a couple of days ago. I decided to play on hypixel, but the authentication servers are down I'm guessing i went to change my skin only to find that it is still a Steve in single player. My friend shortly invited me to a survival game and my skin was normal, he also invited me to play DropBlocks with him, my skin was normal again there. I'm not sure what happened but this morning i decided to make new skin, (see image below). This time my skin was still Steve for single player, it was my second skin on DropBlocks and my newest skin on Herobrine.org
