My server is on Paper 1.20.2 and it shows all the help commands and they all function like normal and I gave myself permissions to use but still can't get it to actually function in an anvil.

I apologize in advance for the possibly clumsy translation, because I do not know English and use a translator. When removing the enchantment from an item, the NBT-tag "repaircost" remains on it, which makes all subsequent actions with this item more expensive. I really want to add a function to config with which you can reset the repaircost when removing enchantments from item

I added this plugin to my server and for some reason the server lists it as working but when I try any commands from it, they don't work.
https://mclo.gs/Mx8GYiO - Here is the log.

I installed the plugin but unfortunately it didn't work, I'm using ecoenchant I don't know if it's compatible
