WPF Datagrid [System.Windows.Datenfehler: 4]

Ich habe eine WPF Anwendung mit einem DataGrid wie unten gezeigt:

Datagrid (vereinfachte):

<DataGrid x:Name="CoreServiceLogDataGrid"
Grid.Row="0"
Height="auto"
ItemsSource="{Binding Source={StaticResource CoreServiceCollection}}"
AutoGenerateColumns="False"
CanUserReorderColumns="True"
CanUserSortColumns="True"
IsReadOnly="True">

    <DataGrid.Columns>
        <DataGridTextColumn x:Name="ID"
            Header="ID"
            Binding="{Binding ID}" />

        <DataGridTextColumn Binding="{Binding Timestamp}"
            Header="Timestamp" />

    </DataGrid.Columns>

</DataGrid>

wenn die Daten geladen, bekomme ich die folgende Fehlermeldung (mehrfach):

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Controls.DataGrid', AncestorLevel='1''. BindingExpression:Path=AreRowDetailsFrozen; DataItem=null; target element is 'DataGridDetailsPresenter' (Name=''); target property is 'SelectiveScrollingOrientation' (type 'SelectiveScrollingOrientation')
System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Controls.DataGrid', AncestorLevel='1''. BindingExpression:Path=HeadersVisibility; DataItem=null; target element is 'DataGridRowHeader' (Name=''); target property is 'Visibility' (type 'Visibility')

Ich habe Keine Ahnung, warum dies geschieht und wie dies zu BEHEBEN.

EDIT: (Info über CoreServiceLogViewCollection)

CoreServiceCollection ist nur eine ListCollectionView.

  public static ListCollectionView CoreServiceLogViewCollection {
        get {
            if (_coreServiceCollection == null) {
                _coreServiceCollection =
                    new ListCollectionView(LogSession.CoreServiceLogCollection);
            }

            return _coreServiceCollection;
        }
    }

der parameter ist nur ein ObservableCollection mit ID,Timestamp und andere Eigenschaften

EDIt2:
Die Instanziierung erfolgt in der App.xaml:

   <ResourceDictionary>
       <x:Static Member="vm2:CoreServiceLogView.CoreServiceLogViewCollection"
                          x:Key="CoreServiceCollection" />
   </ResourceDictionary>
