WPF Binding Warnings

Все, я вижу ниже. Предупреждения в окне "Выход". Может кто-нибудь, пожалуйста, объясните, в чем проблема с Binding здесь. Я установил несколько значений для ProgressValue 'в моей ViewModel. Но для "ProgressValue" установлено только конечное значение 100, как показано ниже.

Мой код показан ниже. Он определен в Styles.xaml.

<ProgressBar IsIndeterminate="False" 
             Value="{Binding ProgressValue, 
                     UpdateSourceTrigger=PropertyChanged, 
                     Mode=TwoWay, 
                     diag:PresentationTraceSources.TraceLevel=High}"
             x:Name="ExportProgressBar"
             Visibility="Collapsed"
             VerticalAlignment="Stretch" HorizontalAlignment="Stretch"
             Background="Transparent"
             BorderThickness="0"
             Foreground="{StaticResource HighlightBlueBrush}"
             />

В моей модели просмотра я обновляю значение, как показано ниже.

                Dispatcher.CurrentDispatcher.Invoke(new Action(() =>
                {
                    export.ProgressValue = pMeter;
                }));
