GTA IV Leaderboards not updating on Xbox

[Guest]

I am trying to unlock all of the achievements on GTA IV, and I am down to the multiplayer ones. I played and won a game of Car Jack City and Team Car Jack City and the leaderboard did not update for them. I played Mafiya Work, and it did update for that game mode, however. I need these game modes for “Aud Wiedersehen Petrovich” and “Taking It For The Team”. My friend who was helping me boost also did not have his stats for those two game modes update. I am playing the game backwards compatible for Xbox Series X. If anyone has any idea how to fix this, I would greatly appreciate it. Microsoft has no ability to fix this issue, and I currently have a support ticket in to Rockstar.
