Characters have to be recreated Everytime I sign in to a game. The character I saved on my account does not apply when I sign into a game.

My husband and I both own a copy of Minecraft so we usually play on his account since he owns the Xbox, I have made a character on my account that I want to use whenever I play however it does not upload when I sign in to play with him, even the character I make each time playing with him will not permanently save like his does, his even has to be redone every now and again. I'm not sure what beta version
