Xaml GridView分组未正确显示

我有一个群组视图。它保存联系人信息，除以每个联系人姓氏的第一个字母

我根据数据创建了CollectionViewSource（contactCVS）（这是正确创建的）

然而，数据出现了一个问题：第二组数据被切碎

此GridView的XAML代码附在下面

            <GridView x:Name="contactsGroupGridView"
                      ItemsSource="{Binding Source={StaticResource contactCVS}}"
                      ItemTemplate="{StaticResource ContactListTemplate}"

我不完全清楚您遇到了什么样的问题。你能提供一个屏幕截图来澄清这个问题吗？
