In an effort to customize the summary row appearance to a flatter row appearance, I am modifying some content templates on DataPresenterGeneric_Express.xaml. One of my gols is to remove the summary description from each summary cell, which I accomplished Changind the property bound to the textblock marked below:

    <!-- _________________________ SummaryResultPresenter ______________________________________ -->
    <Style TargetType="{x:Type igDP:SummaryResultPresenter}">
        <Setter Property="Padding" Value="1,1"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type igDP:SummaryResultPresenter}">
                    <Border
                        Background="{TemplateBinding Background}"
                        BorderBrush="{TemplateBinding BorderBrush}"
                        BorderThickness="1"
                        Padding="{TemplateBinding Padding}"
                        ToolTip="{Binding Path=SummaryResult.ToolTipResolved, RelativeSource={RelativeSource TemplatedParent}}">
                        <!-- SSP 3/19/10 - Optimizations
                            Changed the binding to bind to the new DisplayTextAsync instead of the DisplayText so we
                            don't force synchronous calculation of the summary if it's dirty.
                        -->
                        <TextBlock Text="{Binding Path=SummaryResult.ValueAsync, Mode=OneWay, RelativeSource={RelativeSource TemplatedParent}}"/>
                        <!-- MF <TextBlock Text="{Binding Path=SummaryResult.DisplayTextAsync, Mode=OneWay, RelativeSource={RelativeSource TemplatedParent}}"/>-->
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
        <Setter Property="Margin" Value="0,0,0,2"/>
    </Style>

This may require a converter, but that is besides the point of this question.

STUFF IMPORTANT TO THIS QUESTION:

As seen on the screen shot attached, the summary is not aligned with the data on the source column.

Using .NET Inspector I could verify SummaryResult.SummaryuDefinition.Position set to Default and PositionFieldName not set.( please see attached screen shot)

According to the inline documentation found on VS object browser Default is same as UseSummaryPositionField:

UseSummaryPositionField
    Member of Infragistics.Windows.DataPresenter.SummaryPosition

Summary:
Position the summary in the summary record aligned with the field specified by the Infragistics.Windows.DataPresenter.SummaryDefinition.PositionFieldName property. If SummaryPositionField is not set then the summary will be aligned with the summary’s Infragistics.Windows.DataPresenter.SummaryDefinition.SourceFieldName.

QUESTION: Did I find a bug or what am I missing?

Thanks,

Please ignore the left column summary issue seen on the screenshot below. It is irrelevant to this question.
