Can't Remove Completed Game In GKTurnBasedMatchmakerViewController

After presenting the GKTurnBasedMatchmakerViewController, it displays completed games and when I slide to the right to remove one and then tap Remove, the game disappears & than reappears.

If I then do that once more I get this error:

[Error] Extension request interrupted with error: Error Domain=ExtensionErrorDomain Code=-5900 "(null)"

If I close & re-open the game, that completed match is still listed. The removal process only works if I tap the "i" button and then tap the Remove button.

I'm not sure what could be causing this other than a bug with GameKit? Or I've incorrectly set a delegate, or I haven't added a callback of some kind? Here is the code I'm using to present the VC:

@IBActionfunc StartMultiplayerMatch () {
       
        GKLocalPlayer.local.unregisterAllListeners()
        GKLocalPlayer.local.register(self)
       
        let RequestMatch = GKMatchRequest()
        RequestMatch.minPlayers = 2
        RequestMatch.maxPlayers = 2
        RequestMatch.playerGroup = 1
     
        let gameCenterVC = GKTurnBasedMatchmakerViewController(matchRequest: RequestMatch)
        gameCenterVC.turnBasedMatchmakerDelegate = self
        present(gameCenterVC, animated: true, completion: nil)
   
    }

Any help would be very much appreciated, as I'm very much stuck with this and feel my next step will have to be using a developer technical support ticket.
