"invalid" pvp bracket for classic leaderboard

The following API call https://us.api.blizzard.com/data/wow/pvp-region/1/pvp-season/7/pvp-leaderboard/index?namespace=dynamic-classic-us&locale=en_US&access_token=__token__ provides the output

...
{
      "key": {
        "href": "https://us.api.blizzard.com/data/wow/pvp-region/1/pvp-season/7/pvp-leaderboard/3v3?namespace=dynamic-classic-us"
      },
      "name": "3v3",
      "id": 1
    },
    {
      "key": {
        "href": "https://us.api.blizzard.com/data/wow/pvp-region/1/pvp-season/7/pvp-leaderboard/invalid?namespace=dynamic-classic-us"
      },
      "name": "invalid",
      "id": 2
    }
...

Of which, “invalid” is not a valid bracket, but this appears to be the 5v5 bracket?

Subsequent API requests can be made with this “invalid” name which is incorrect, and the bracket should be named correctly.

Please could this be resolved - Thanks!
