I'm not sure why this box appears above my headers, but it does. I'm able to click on it and it brings up the GroupPicker view, however it doesn't have any letters on it.

Hi Justin,

Thanks for writing and for the shared code.

The reason for this behavior is that you're overriding the JumpList's style. The new style that you're setting does not have some of the template parts needed by the JumpList and therefore the logic that handles the StickyHeader element fails.

You can still hide the JumpList's sticky header by setting the Visibility property of the corresponding template part within the Control's template (PART_StickyHeader). You can also extract the default JumpList style using the Visual Studio designer and modify it accordingly. It should contain all missing template parts.

I hope this helps.
