"none" being added to the end of chat messages.

After setting up buycraft on my server and deopping myself to try it out, I found that every time I put a message in chat, there would be a "none" after it. I then tried opping myself and the none dissapeared.

Here is a list of my plugins:
LuckPerms, LeakParkour, ColoredSigns, ItemToCommand, VoidWorld, PerWorldPlugins, PlugMan, BuycraftX, FastAsyncWorldEdit, Sudo, CrispyDisguise, ViaVersion, Vault, WorldEdit, Essentials, CreateYourOwnMenus, WorldGuard, ProtocolLib, Citizens, ASkyBlock, EssentialsChat, SuperVanish, WorldGuardExtraFlags, HolographicDisplays, Multiverse-Core, CitizensCMD, Multiverse-Inventories, Multiverse-Portals, HubBasics

Please help.

 

It only appears to happen in the hub world. Example:

 

I looked through the Multiverse, Essentials and HubBasics config and Ctrl-F'ed for "none" but I couldn't find anything.
I looked in
HubBasics: config.yml & messages.yml
Essentials: config.yml
Multiverse: config.yml & worlds.yml

 

This is my PerWorldPlugins config

exempt-login-events: true
check-for-updates: true
blocked-msg: '&c[Error] This command cannot be performed in this world.'

Thanks, I will try the Multiverse thing, but what do you mean by "verbose feature"?
