Deleted world comes back when re-enter game.

hello, I'm having problems when I delete a world in Mine, when I delete a world it deletes normal, but when I leave the game and enter again the world comes back again, I tried to restart the game, and the device tried to reinstall the game and delete the profile data but the problem remains and another detail when I enter the game the worlds are gray needing to sync more but when I click enter the world it gives sync error 😞
