Matchmaker Queue Issue

Hi!
I am facing a issue where when two players create ticket, sometimes the matchmaker does not allocate them a server. When a third player creates a ticket, somehow all 3 players join the same server causing the third player to find themselves unable to do anything as server is full.My Queue is made for 1v1 matchmaking only and I am sharing my Queue Rule JSON below.

{
  "Name": "1v1",
  "MatchDefinition": {
    "Teams": [
      {
        "Name": "Teams",
        "TeamCount": {
          "Min": 2,
          "Max": 2,
          "Relaxations": []
        },
        "PlayerCount": {
          "Min": 1,
          "Max": 1
        }
      }
    ],
    "MatchRules": []
  },
  "BackfillEnabled": false
}

I would check for sanity is that 2 of the players don’t have the same userID. Potentially what’s happening is 2 of the clients have the same userID, so they are not getting matched against each other. But when the third client queues with a different userID, it’s popping the queue of the first 2 since they are basically the same player.

Hey jack, I checked the ID’s and player Id’s are unique as its Anonymous Sign In. Do you have any other idea on what to do to resolve this.
