Changing difficulties but no matter how many times I try changing it, it stays on hard

[dxisyyy]

I've been wanting to change the difficulty back to normal and when I do that on the website it still shows in game that the 

difficulty is hard, I followed the tutorial given by the official Minehut YouTube channel but regardless of that, it still will not work. Does anyone know a way to fix this? If so, please reply as soon as possible

 

ps. yes, I did op myself.

Have you tried changing it in-game? Do you have OP?
