chests and item frames badly broken

After the new update, I got on the Minecraft windows 10 edition and found this weird glitch with all of my chests. I don't know what happened. The dragon head and Item frames are also glitched and have distorted textures.

Edit: Another thing I've noticed is that every time I go on the world, it's a new thing that gets the bugged texture. a couple of minutes ago it was signs now its shulker boxes. It may also help to mention that it is on EDU mode.
