FarLands Appeared In 1.14 World

I was just about to join in my favorite creative mode world when all of a sudden, the world name switched to My World and all the world settings were different. I joined the world and just about to work on one of my buildings, the FARLANDS loaded. I was in a flat world, Xbox One, and version 1.14. I don’t know HOW it happened but the My World world WAS the FarLands. The original world was completely fine but all surrounding it, it’s the FarLands. I will update this bug and put a picture later today.
