Hi Rashad Rivera,
We are sorry for your frustration. We managed to reproduce the issue and we will do our best to fix it for SP1. We are glad that you have found a workaround, you can also copy the templates from the Themes solution that is included in our installation. The predefined dialogs templates are in RadWindow.xaml.
Please, excuse us for the inconvenience. We have added points to your account for the report.
