我目前有一个集合视图，它显示从我设备中的本地数据库中提取的记录列表。数据库工作正常，添加记录、删除记录都工作正常。问题是当我添加或删除记录时，当集合视图被刷新时，它显示的是每个现有记录的副本。奇怪的是，如果我再次刷新，它将返回到正常状态，并且只显示从中提取的数据库中的表的记录。
这是我的观点模型：

[QueryProperty(nameof(Players), "Players")]
    public partial class ManagePlayersPageViewModel : ObservableObject
    {
        /// <summary>
        /// List of players being displayed 
        /// </summary>
        private ObservableCollection<Player> _players = new();
        public ObservableCollection<Player> Players
        {
            get => _players;
            set => SetProperty(ref _players, value);
        }

        [ObservableProperty] private bool isRefreshing;

        /// <summary>   
        /// Options for selection modes
        /// </summary>
        public SelectionOptions SelectionOptions { get; } = new();

        /// <summary>
        /// Adds player to list
        /// </summary>
        /// <returns></returns>
        [RelayCommand]
        async Task AddPlayer()
        {
          var task =  await Shell.Current.ShowPopupAsync(new AddPlayerPopup());
          var player = task as Player;

          if (task == null)
              return;

          if (await PlayerService.RecordExists(player))
          {
              await Shell.Current.DisplaySnackbar("Jugador ya existe");
              return;
          }
          
          await PlayerService.AddAsync(player);
          
         
          await Refresh();
        }

下面是refresh（）方法：

/// <summary>
        /// Refreshs and updates UI after each database query 
        /// </summary>
        /// <returns></returns>
        [RelayCommand]
        async Task Refresh()
        {
            IsRefreshing = true;
            await Task.Delay(TimeSpan.FromSeconds(1));
            Players.Clear();

            var playersList = await PlayerService.GetPlayersAsync();
           
            foreach (Player player in playersList)
                Players.Add(player);

            IsRefreshing = false;
        }

下面是控件所在的xaml：

<RefreshView Grid.Row="2" Grid.Column="0" Grid.ColumnSpan="3"
               IsRefreshing="{Binding IsRefreshing}"
               Command="{Binding RefreshCommand}">
                <CollectionView
                    ItemsSource="{Binding Players}"
                    SelectionMode="{Binding SelectionOptions.SelectionMode}">
                    <CollectionView.ItemTemplate>
                        <DataTemplate>

                                    <SwipeItems>
                                        <SwipeItemView 
                                            Padding="0, 2.5"

                                            CommandParameter="{Binding .}">
                                            <Border

                </CollectionView>
           </RefreshView>

知道为什么会发生这种情况吗？注意：数据库在上一页被查询，并作为参数传递到集合视图所在的页，不知道这是否与它有关。注意：它曾经与列表视图控件一起工作得很好，但我没有那么多的灵活性来定制该控件，这就是为什么我要走使用集合视图的路线。
当我调试时，它显示setter中的值已经重复，但我不知道为什么或在哪里重复。只有当我添加或删除记录时才会发生这种情况。任何帮助都是感激的，谢谢！
