WP 8.1 XAML: cost does not fall within the expected range

Question

I encountered an annoying error in my Windows Phone 8.1 Runtime application. The error occurs when I defined my CommandBar on my page. This bar has been there almost since the creation of the application, but now the designer decided to make it a mistake. It reports an error like "The value is not in the expected range." Here is the code:

<Page.BottomAppBar>
    <!-- ERROR STARTS HERE --><CommandBar x:Name="ButtonBar" Background="{StaticResource StrikeDistanceThemeBrush}" Foreground="{StaticResource StrikeDistanceForegroundBrush}" BorderBrush="White">
        <CommandBar.SecondaryCommands>
            <AppBarButton x:Name="SettingsButton" Label="settings" Click="SettingsButton_Click"/>
            <AppBarButton x:Name="AboutButton" Label="about" Click="AboutButton_Click"/>
            <AppBarButton x:Name="AppsButton" Label="more apps"/>
            <AppBarButton x:Name="RateButton" Label="rate+review"/>
        </CommandBar.SecondaryCommands>
        <AppBarButton x:Name="CalculateButton" Label="calculate" Click="CalculateButton_Click" Icon="Calculator"/>
        <AppBarButton x:Name="ClearAllButton" Icon="Clear" Label="clear all" Click="ClearAllButton_Click"/>
        <AppBarButton x:Name="HelpButton" Icon="Help" Label="help"/>
    </CommandBar><!-- ERROR ENDS HERE -->
</Page.BottomAppBar>

In addition, the CommandBar appears during debugging of the application, except that items that are normally pushed (for example, an AdDuplex control) do not move. So far, these have failed :

• Reboot Visual Studio
• Restart the computer.
• Create a new CommandBar

Thank you for your help!
