i mean, example: 2 item A and B, with same name "- name:&f&l64 This Name", but in different inventorylocation, like this
InventoryLocation: 3 and InventoryLocation: 4, so only item in InventoryLocation: 4 are show in GUI.
Known issue. Might be fixed soon but meanwhile you can as workaround simply add &0-&9 at the end of the name in order to avoid the names from being equal.
