Hoppers not working

[Enttixie]

Hello! I've been using this nice plugin quite a while, however, the hopper's pickup thing is not working. When config's is set to NONE, the hopper still picks up the item. When set to PLACER or KILLER, the hopper does not add the value into the player's balance.

MoneyFromMobs version: 4.6

My config:
HopperGivesMoneyTo: NONE

Server version:
This server is running Paper version git-Paper-387 (MC: 1.18.2) (Implementing API version 1.18.2-R0.1-SNAPSHOT) (Git: df630a2 on ver/1.18.2)

Any help would be appreciated.
If it's lacking info, please let me know :)
