Focus on unselected listViewitem

Question

I have 2 listViews as shown below. When I select an item in the first listView it gets Highlighted, but when I select an item in the second listView, the first selected item from the first listView losses its highlightning. I dont want this to happen, I want both items to be highlighted. Any help?

<ListView x:Name="listViewDevice" ItemsSource="{Binding NotMappedInputAttributes}" KeyboardNavigation.TabIndex="6" SelectedItem="{Binding SelectedInputAttribute}" Grid.Column="2" Margin="5,27,5,32" Grid.Row="1" Grid.ColumnSpan="2">
            <ListView.ItemContainerStyle>
                <Style TargetType="ListViewItem">
                    <Setter Property="HorizontalContentAlignment" Value="Stretch" />
                </Style>
            </ListView.ItemContainerStyle>
            <ListView.View>
                <GridView>
