Essentials by default let me enchant everything but with the command /enchant and a different syntax than the original enchant command. This bug is very annoying because I need to create special items for my community (I'm a server owner) and don't know why this happens. Pastebin: https://pastebin.com/a9p1vZWw

EssentialsX has always had its own /enchant command. If you want to use the vanilla command, use /minecraft:enchant.
