Problem Iridium ore generation

[Petruche]

Hello!
I'm using Infinity Evolved FTBInfinity-2.2.2-1.7.10 (I deleted some mods but remained Nether ORES)

Can not add generation iridium ore. Add to \FTBInfinityServer\config\cofh\world\FTB-Infinity-Ores.jason

Spoiler: FTB-Infinity-Ores.jason

"Iridii": {
"template": "normal",
"block": "NetherOres:tile.netherores.ore.1:3",
"material": "minecraft:netherrack",
"clusterSize": 2,
"numClusters": 1,
"meanHeight": 33,
"maxVariance": 3,
"retrogen": "true",
"biomeRestriction": "none",
"biomes": [],
"dimensionRestriction": "none",
"dimensions": []
},

But when the server receives an error:

Spoiler: Console

[13:40:59] [Server thread/ERROR] [CoFHWorld]: Invalid block entry!
[13:40:59] [Server thread/WARN] [CoFHWorld]: Template 'normal' failed to parse i
ts entry!
[13:40:59] [Server thread/ERROR] [CoFHWorld]: Error parsing generation entry: "I
ridii" > Please check the parameters. It *may* be a duplicate.

Similarly, added a platinum ore, it works

What could be the problem?

P.S. Sorry for bad english)

iridium only spawns in the over world and that magical forest biome.
