Is this how it supposed to look when using DisplayStartDate in CalendarDatePickers?

[sukhman-jot-singh]

<CalendarDatePicker
			   Background="{DynamicResource BackgroundColor}"
							IsTodayHighlighted="True"
	                        HorizontalAlignment="Left"
							DisplayDateStart="{Binding LatestDateOfStartingValue}"
	                        SelectedDate="{Binding StartingOn}"
	                        Width="255"
	                    />

Should't they be grayed out or crossed something. I looked in the source code and there are some cross icons, the are not visible anywhere.

How can I get to have grayed out icons. I am not able to reverse-engineer it. I tried this. But it didn't work

<Style Selector="CalendarDayButton:blackout /template/ Path#BlackoutVisual">
		    <Setter Property="IsVisible" Value="True" />
		    <Setter Property="Opacity" Value="1" />
		    
	    </Style>

	    <Style Selector="CalendarDayButton:blackout /template/ ContentPresenter#ContentPresenter">
		    <Setter Property="Opacity" Value="1" />
	    </Style>

	    <Style Selector="CalendarDayButton:blackout">
		    <Setter Property="IsHitTestVisible" Value="False"/>
	    </Style>
