GetLeaderboardAroundPlaye() doesn't return the players around the player.
"PlayFab unique identifier of the user to center the leaderboard around."
Instead it always returns the players in front of the player, no matter the setup of the request. The player is always the last in the list and has the highest position.
Code, just in case:
// Leaderboard around player GetLeaderboardAroundPlayerRequest requestLeaderboardAroundPlayer = new GetLeaderboardAroundPlayerRequest() { StatisticName = name, MaxResultsCount = 10 };
