What I have tried

I have updated all plugins and tried to see if I could fix it in the configs. I am not sure if it's a plugin bug or something wrong in the configs. It worked on 1.20.4 before I updated. Still works but some items like the Potion Switcher and other things don't work.

Screenshot of /kp debug

Any additional information (copy of config files, screenshots, videos, etc.)
You can try it out on: play.minearchy.com

I was unable to replicate this bug. Do you know what the player(s) were doing when this bug occurred?
