Cannot create item already exists

Zabbix 2.4

I created an item prototype for a LLD discovery. I'm getting the following error message:

Cannot create item: item with the same key "echo.ts[{#ObjectName}]" already exists.

What is wrong with the item definition ? Is there is a problem with the LLD data ?

The json LLD data is below:

{
"data":[

{
"{#ObjectName}": "fcud02",
"{#LineBPort}": 10002,
"{#LineAAddress}": "ts01nyc",
"{#RtuNumbers}": [
88,
89,
90,
91,
92,
93,
95
],
"{#SlaveAddressess}": [
2,
3,
4,
5,
6,
7,
8
],
"{#B1Names}": [
"166CIR",
"186CIR",
"207CIR",
"219CIR",
"237CIR",
"248CIR",
"263CIR"
],
"{#LineBAddress}": "ts02nyc",
"{#DiagnosticPort}": 50831,
"{#TraceFileName}": "/home/logs/fcud/fcud.125thSt.log",
"{#LineAPort}": 10002
}

]
}

Macros are in capital letters. Replace {#ObjectName} with {#OBEJCTNAME} etc.
Currently it takes it literally and not as LLD macro.

Hey Thanks. That worked making it capital.
