When you exit the world it is automatically deleted from consel and cloud

I recently got a problem where the tile drops on my servival world would disappear when I approched them. That would have been ok if not for the fact that once I exited the world the world just disappeared, gone from both my consoles memory and my cloud back up. I do not know what to do as all of the backs up for that world that where in servival have all been deleted without my permission. Every world that is not in creative gets the same bug items disappeariing world is automatically deleted when I exit. 

Befor I forget all the worlds that I have lost are under 60mb in size. Please fix this all of my work has gone down a drain I am use to having redstone heavy world get corrupt and become unplayable but not for normal non redstone world to just disappear.
