Ribbon Office 2013

llo! I am using the following code for my program. I want it to look like Office 2013, you should only add the reference to the project that comes with WPF 4.5 and is System.Windows.Controls.Ribbon. I have a problem, when I select one tab, her border, its not completed.

x:Class="WpfApplication1.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" WindowStartupLocation="CenterScreen"> TargetType="Ribbon"> Property="Background" Value="White"/> Property="Foreground" Value="Black"/> TargetType="RibbonGroup"> Property="Background" Value="Transparent"/> TargetType="RibbonTabHeader"> Property="Background" Value="White"/> Property="BorderBrush" Value="Transparent"/> Property="FontSize" Value="13"/> Property="Padding" Value="15,2,15,2"/> Property="BorderThickness" Value="1,1,1,5"/> Property="Margin" Value="1,0,1,0"/> Property="Template"> TargetType="RibbonTabHeader"> x:Key="CheckedBackground" Color="#FFF5F6F7"/> x:Key="CheckedBorderBrush" Color="#FFDBDCDD"/> Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}"> Margin="{TemplateBinding Padding}" HorizontalAlignment="Center" VerticalAlignment="Center" RecognizesAccessKey="True"/> Property="IsRibbonTabSelected" Value="True"> Property="Background" Value="{DynamicResource CheckedBackground}"/> Property="BorderBrush" Value="#FFB9C9DA"/> Property="Foreground" Value="Blue"/> Property="IsMouseOver" Value="True"> Property="Foreground" Value="Blue"/> Header="INICIO"> Header="Portapapeles"> Label="Hola" LargeImageSource="Imágenes/Artículo.png" Height="Auto" VerticalAlignment="Top"/> Header="Fuente"> Content="Fuente"/> Header="INSERTAR"/> Header="DISEÑO"/> SmallImageSource="Imágenes/Usuario.png"> Width="Auto" Header="Iniciar sesión..." ImageSource="Imágenes/Usuario.png"/> Width="Auto" Header="Cambiar contraseña..." ImageSource="Imágenes/Usuario.png"/> Width="Auto" Header="Cerrar sesión..." ImageSource="Imágenes/Usuario.png"/>

Attached 2 images, the first is what I get done, the other is what I would like.
