gauge is not labelled because it does not come back as a preferential gauge in the old subgraph, and is therefore ignored by the address book. will be solved by BalancerMaxis/bal_addresses#399

it is however the correct gauge.

old subgraph results:

{
  "data": {
    "liquidityGauges": [
      {
        "id": "0xbdbc27a1c245ed52eacb0dc6eba922992328f303",
        "symbol": "BCoW-50ARB-50WETH-gauge",
        "isPreferentialGauge": false
      }
    ]
  }
}

apiv3:

{
  "data": {
    "poolGetPool": {
      "staking": {
        "gauge": {
          "gaugeAddress": "0xbdbc27a1c245ed52eacb0dc6eba922992328f303"
        }
      }
    }
  }
}
