Bug Fix: Fixed a bug with player ShopShelves acting up on setting up items.
New Feature: Player ShopShelves now have a new setting (limit_playershelf_to_single_type) in the config by default on true if set to false it will allow players to use 3 different item types in 1 player ShopShelf.
My first upload was a spigot only plugin which i quickly fixed to have paper support i uploaded the second version correctly to modrinth but forgot to update spigot i am sorry for the inconvenience!
