My worlds are bugging out

So I have a server the next and my friends will play on a lot and so randomly another world was added to my server named “world” and I can’t delete it and whenever you join the server it brings you to “world” instead of the main one and idk what to do could someone help me.

For more context it’s a Bedrock server idk if that information is needed but might as well say it

That did the trick, thanks for telling me!
