语义缩小视图与Windows Phone 8.1中的另一个缩小视图重叠

Question

我有5个支点项目。在每个视图和视图中都有语义缩放，当我进行语义缩小视图时，它与另一个语义缩小视图屏幕重叠。 如何解决这个问题。

这是我的代码：

 <Grid Margin="0 -15 0 0" Grid.RowSpan="2" x:Name="MainGrid">
        <Pivot x:Name="PivotControl" x:Uid="PivotControlTitle" PivotItemLoaded="PivotControl_PivotItemLoaded"  Visibility="{Binding PivotControlVisibility}">
            <PivotItem Margin="20 10 15 10" Tag="0">
                <SemanticZoom  IsZoomedInViewActive="{Binding IsSZoomedInViewActive, Mode=TwoWay}">
                    <SemanticZoom.ZoomedInView>
                        <GridView
                        AutomationProperties.AutomationId="ItemsGridView"
                        AutomationProperties.Name="Grouped Items"
                        SelectionMode="Multiple"
                        ItemTemplate="{StaticResource fileItemControl}"
                        ItemsSource="{Binding Source={StaticResource groupItemViewSource}}"
                        IsSwipeEnabled="True"
                        >
                            <GridView.GroupStyle>
                                <GroupStyle HidesIfEmpty="True">
                                    <GroupStyle.HeaderTemplate>
                                        <DataTemplate>
                                            <TextBlock
