is there a way to get this prefix message to not show ?

 "Chat/Message prefix": "[ZTL Drop Services]",
    "Prefix color": "#00ffff",
    "Prefix format": "<size=12><color={0}>{1}</color>: ",

IThe server literally shows what show above, I want it to announce the ZTL Service Drop but i dont want it to show the actual prefix as a message

Yes just change it to whatever or nothing like ""

so if I do this then it will be ok

"Prefix color": "#00ffff",
   "Prefix format": "<size=12><color={0}>{1}</color>: ",​

TO
"Prefix color": "#00ffff",
"Prefix format": "",

no see below, the other part is the size of the text and color.

"Chat/Message prefix": "",
   "Prefix color": "#00ffff",
   "Prefix format": "<size=12><color={0}>{1}</color>",
