Cape and Elytra Glitch

I was playing with my elytra after I downloaded my new Minecon 2016 cape. Just to see what would happen, I turned off the Capes setting in Skin Customization. I went back in-game, and tried putting on my elytra again. When I did, the elytra was the wrong texture. Instead of the normal elytra texture, it was the image of all the items and blocks in-game.
