The following code works as long as I only test one trigger. When I began adding single buttons into each cell, everything seemed fine. However, the issue arose when I added one cell with two buttons and unexpectedly, all other cells also received double buttons

<DataGridTemplateColumn Header="Signal" CanUserResize="False" CanUserReorder="False" Width="80" MaxWidth="80"  HeaderStyle="{StaticResource CenterGridHeaderStyle}">
                            <DataGridTemplateColumn.CellStyle>
                                <Style TargetType="DataGridCell">
                                    <Style.Triggers>
                                        <DataTrigger Binding="{Binding DataContext.ShowDoubleButton, RelativeSource={RelativeSource AncestorType=DataGrid}}" Value="True">
                                            <Setter Property="BorderBrush" Value="Gray"/>
