Duplicate worlds

I recently purchased new game packs on console (Xbox) and my legacy world now has duplicate worlds of only the new game pack worlds. I purchased business and hobbies, love struck, get together, and cats and dogs. I already redownload the games and downloaded each pack that I own one by one yet it still duplicates. On other saves it’s fine it’s just on my legacy world which sucks! Is there anyway to fix this issue because not only there’s duplicate worlds but it’s extremely buggy. Also I wanted to note I don’t have any mods on my game since it is console so it’s not like maybe I mod I downloaded is causing these effects.
