Game ID / name pairing not consistent / correct across helix and v5

A slightly different example involving the top_games endpoint returning a ID/name mismatch:

Time called: "2019-08-29T21:30:02+00:00" (GMT)
Endpoint: https://api.twitch.tv/kraken/games/top? (offset not recorded)
Response at the point of interest (JSON turned into ruby hash):

    {
      "game" => {
        "name" => "Star Trek Trexels",
        "popularity" => 0,
        "_id" => 511981,
        "giantbomb_id" => 73202,
        "box" => {
          "large" => "https://static-cdn.jtvnw.net/ttv-boxart/Star%20Trek%20Trexels-272x380.jpg",
          "medium" => "https://static-cdn.jtvnw.net/ttv-boxart/Star%20Trek%20Trexels-136x190.jpg",
          "small" => "https://static-cdn.jtvnw.net/ttv-boxart/Star%20Trek%20Trexels-52x72.jpg",
          "template" => "https://static-cdn.jtvnw.net/ttv-boxart/Star%20Trek%20Trexels-{width}x{height}.jpg" },
        "logo" => {
          "large" => "https://static-cdn.jtvnw.net/ttv-logoart/Star%20Trek%20Trexels-240x144.jpg",
          "medium" => "https://static-cdn.jtvnw.net/ttv-logoart/Star%20Trek%20Trexels-120x72.jpg",
          "small" => "https://static-cdn.jtvnw.net/ttv-logoart/Star%20Trek%20Trexels-60x36.jpg",
          "template" => "https://static-cdn.jtvnw.net/ttv-logoart/Star%20Trek%20Trexels-{width}x{height}.jpg"
        },
        "localized_name" => "Star Trek Trexels",
        "locale" => "en-us"
      }, 
      "viewers"=>8, 
      "channels"=>1
    } 

Except that
https://api.twitch.tv/helix/games?name=Star Trek Trexels returns

{
    "data": [
        {
            "id": "512421",
            "name": "Star Trek Trexels",
            "box_art_url": "https://static-cdn.jtvnw.net/ttv-boxart/Star%20Trek%20Trexels-{width}x{height}.jpg"
        }
    ]
}

and https://api.twitch.tv/helix/games?id=511981 returns

{
    "data": [
        {
            "id": "511981",
            "name": "Drunken Wrestlers 2",
            "box_art_url": "https://static-cdn.jtvnw.net/ttv-boxart/Drunken%20Wrestlers%202-{width}x{height}.jpg"
        }
    ]
}

So looking at the top_games response, I have no idea whether the game that was being played was "Star Trek Trexels" or "Drunken Wrestlers 2". Typically in the past with v3 and v5, the "name" field was more reliable and other endpoints relied on passing the game name. But I’ve never seen a complete mismatch like this before recently.
