Switching MaterialLight or MaterialDark crashes the application

Hi,

i have some problems using the Themes created by Theme Studio.

To demonstrate i have attached a small application.

1. Please use your copy of MaterialDark and MaterialLight and insert it as a reference.
2. The application starts with Office2016Gray
3. Select MaterialLight or MaterialDark and you will see some nice "Bably Blue" screen, i assume it is some Office Blue theme, but it doesn't reflect Light or Dark
4. Now unselect "ApplyStyleOnApplication"
5. Change now e.g. Office2016Gray and then back to MaterialLight or MaterialDark
6. Application crashes with: 
    System.Windows.Markup.XamlParseException: ''{DependencyProperty.UnsetValue}' is not a valid value for property 'Background'.'


Another problem is if you want to use MaterialLight or MaterialDark as default theme in the xaml.
i.e. skin:SfSkinManager.VisualStyle="MaterialDark"   in MainWindow.xaml.

This throws a:  InvalidOperationException: 'RibbonWindow' TargetType does not match type of element 'MainWindow'.

thanks for looking into this,

Helmut
