Broken player animations

So, my sister and I decided to start a new Minecraft world and we play on Playstation 4 with slip screen. But, when we got enough resources to make a shield and a bed, some weird stuff happened. On my sister's POV, my player model was holding the shield very weirdly and when i sleep in the bed, my player model sleeps in the opposite way of the bed. But that only happens in her POV, because in my POV everything is fine, including in the inventory menu.

Please fix that, it looks dumb.
