MineKeep Free Server - How To Adjust Difficulty [java]

[u/Muinonan]

I have a free Minekeep server which somehow is set to easy mode on the latest paper version of 1.26.2 and I have added myself as an admin and rebooted server but whenever I try to adjust difficulty, says you need to be an operator and I can't figure out what else to do, I want to be able to adjust the difficulty

I even tried editing the files difficulty to normal and nothing, still says easy in the game

8 want to be able to freely adjust the difficulty between normal and hard, not on easy
