Respawn on log in

     On Minecraft bedrock for the Xbox one whenever I save and exit a game and rejoin, I never save even though the saving icon chest disappears. Then if I keep playing the world every day it resets and sometimes will let me start replaying a last saved from before like four days earlier. I am getting tired of not being able to actually progress in the game when everything I get supplies wise is wiped Everytime I save and exit the game. Please fix this.
