Recipe for single item is not registering, all other recipes are.

I cannot find the problem with this one item, but here is the json file for the recipe:

{
    "type": "minecraft:crafting_shaped",
    "pattern": [
        "bdb",
        "bcb",
        "bab"
    ],
    "key": {
        "a": [
            {
                "item": "avp:part.ic",
                "data": 0
            }
        ],
        "b": [
            {
                "item": "avp:part.led",
                "data": 0
            }
        ],
        "c": [
            {
                "type": "forge:ore_dict",
                "ore": "polycarbonate"
            }
        ],
        "d": [
            {
                "type": "forge:ore_dict",
                "ore": "lithium"
            }
        ]
    },
    "result": {
        "item": "avp:part.led.display",
        "count": 1,
        "data": 0
    }
}

It is the 7-Segment LED Display from the Aliens Vs Predator mod for 1.12.2. It neither works in singleplayer or on a server supporting the mod. My knowledge on these types of files is limited, so try to break it down for an average Joe.
