Is this happening every time and with every character? Have you tried re-starting the title like shutting it down completely?
I had tried quitting the game and restarting before... more than twice. It got worse one of those times, but it didn't go away.
So, tonight I rebooted the console again and this time Character Customization is back to normal.
I've had matchmaking issues now instead... (and the game keeps telling me to check my network connectivity, though there's nothing wrong with my network connectivity), but that cleared up after 30-40 minutes. So, it came and went... hopefully, it will stay gone.
I'll update if the "Upside Down Glitch" returns... but for now, it's gone. *knock on wood*
