Hey, im running a PvE server and i want to disable looting by other players that havent called in the drop, as far as i know the below config was working fine, but after having tested it, it doesnt actually work, anything ive done wrong here?

},
"Generic": {
"Admin messages color": "silver",
"AuthLevel needed for console commands": 1,
"Broadcast messages color": "white",
"Chat/Message prefix": "UGN Drop",
"GUI Announce command": "announce.announce",
"Lock DirectDrop to be looted only by target player": true,
"Lock SignalDrop to be looted only by target player": true,
"Prefix color": "cyan",
"Prefix format": "<color={0}>{1}</color>: ",
"Show message to admin after command usage": true,
"Time for active smoke of SupplySignal": 210.0,
"Unlock crates only after player stopped looting": false,
"version": "2.7.8"
},

They are both set to true and are in the config i showed above but players can still loot them if they havent called them in.
