We cannot access that link, as it's your private list of games.
But if I had to bet, you are talking about the Ladder Tournament.
You ask a lot of question about the Ladder Tournament xD
Have you read how that tournament works?
In fact, it could be any kind of tournament. When a tournament starts you are paired with your opponents. Why do you think you should be paired only with people you played before? Why is it a surprise that they are "random"?
