I'm trying to upload a world I made in creative in single player because I used world edit to make my map. for some reason whenever I try to upload it on mine hut it says "An error occurred. Please try again." and when I do /ul world placeholder https://file.io/mJy2R91bt6CF It says upload successful but when I try to join the world with /worlds and /world, it says "that world doesn't exist!"

I can't change the difficulty on a world that isn't the main world. I'm using the /ul command for other worlds. I've tried /difficulty and changing it on minehut but nothing is working.
