Images only showing in last ListBoxItem

This is what I'm building:

Listbox

On the right side of each ListBoxItem there should be 3 images, but as you can see they are only showing up on the last row. I'm using a ContentControl that refers to XAML shapes that I took from SyncFusion Metro Studio (exported as XAML).

Should I be using something else instead?

Here's my XAML:

<ListBox>
    <ListBox.ItemTemplate>
        <DataTemplate>
            <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition
                        Height="auto" />
                    <RowDefinition
                        Height="auto" />
                </Grid.RowDefinitions>
                <DockPanel
                    Grid.Row="0">
                    <TextBlock
                        DockPanel.Dock="Left"
                        Margin="0 0 6 0">
                        <TextBlock.Text>
                            <MultiBinding
                                StringFormat="{}{0:D2}:{1:D2}:">
                                <Binding
                                    Path="Task.Schedule.StartTime.Hours" />
                                <Binding
                                    Path="Task.Schedule.StartTime.Minutes" />
                            </MultiBinding>
                        </TextBlock.Text>
                    </TextBlock>
                    <ContentControl
                        Content="{StaticResource CM.Done}"
                        DockPanel.Dock="Right" />
                    <ContentControl
                        Content="{StaticResource CM.Comment}"
                        DockPanel.Dock="Right" />
                    <ContentControl
                        Content="{StaticResource CM.Important}"
                        DockPanel.Dock="Right" />
                    <TextBlock
                        Text="{Binding Task.Name}" />
                </DockPanel>

                <TextBlock
                    Grid.Row="1"
                    Foreground="Gray"
                    FontStyle="Italic"
                    Text="{Binding Status, UpdateSourceTrigger=PropertyChanged, Converter={StaticResource StatusEnumToStringConverter}}" />
            </Grid>
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>

Here's an example of what 1 image looks like:

<Viewbox
    x:Key="CM.Important">
    <Grid
        Width="24"
        Height="24"

This is normal behavior: you can't have twice the same UI object displayed in WPF. Here you are trying to display multiple instances of the same ViewBox

A common workaround is:

1 - Change your ViewBox Resources to Templates:

<ControlTemplate x:Key="CM.Important" TargetType="{x:Type Control}">
    <Viewbox>
        <!-- Your ViewBox content -->
    </Viewbox>
</ControlTemplate>

2- Change your ContentControls to Controls:

<Control Template="{StaticResource CM.Important}" />

Should work fine for you unless Path is adding some ambiguity

According to your comment, the static resource which you refer to with CM.* are ViewBoxes. A ViewBox is a control and a control can only have one parent. So only the last item has those images.

You should try to convert those resource to a different class which isn't a control. Unfortunately I haven't really worked with paths so I don't know which class would work best for them.
