DevExpress GridControl not showing all data under columns when using dynamic data

Question

I am working with DevExpress GridControl using MVVM this is my *.xaml

<dxg:GridControl x:Name="grid" AutoGenerateColumns="AddNew" ShowBorder="True" SelectionMode="Row" DetectNestedPropertyChanges="True" MaxHeight="{x:Static SystemParameters.PrimaryScreenHeight}" 
     ItemsSource="{Binding Items, Mode=TwoWay}" SelectedItems="{Binding SelectedItems}" CurrentItem="{Binding CurrentItem}" ColumnsSource="{Binding Columns, Mode=TwoWay}" ColumnGeneratorTemplate="{StaticResource DefaultColumnTemplate}"
     AllowColumnMRUFilterList="False" AllowLiveDataShaping="True"
     >

My Items and columns collection in the VM

    public RangeObservableCollection<object> Items
    {
        get => GetValue<RangeObservableCollection<object>>();
        set => SetValue(value);
    }

    public ObservableCollection<Column> Columns
    {
        get => GetValue<ObservableCollection<Column>>();
        set => SetValue(value); 
    }

I have a method call that creates a JSON string and Deserializes it

    public void CreateCollection()
    {
        for (int i = 0; i < 100; i++)
        {
            string json = @"
            {
                ""TagName"": """ + $"TagName{i}" + @""",
                ""User"": """ + $"User{i}" + @""",
                ""TagDateTime"": """ + DateTime.UtcNow.ToString("MM-dd-yyyy HH:mm:ss.fff K") + @""",
                """ + $"Tag{i}" + @""": """ + $"Value{i}" + @"""
            }";
            dynamic tag = JsonConvert.DeserializeObject(json)!;
            
            var d = JsonConvert.DeserializeObject<Dictionary<string, dynamic>>(json)!;
            foreach (var key in d.Keys)
            {
                var column = new Column(key);
                if(!Columns.Contains(column))
                    Columns.Add(column);
            }
            Items.Add(tag);
        }            
    }

DataGrid in the application

As shown in the image the data that comes back only displays the first instance of the dynamic data. If I change the order I can verify that. I am trying to display all the data in each column for each row.
