As I said above, I removed all of the XML files from the ContextMenuMode folder AND cleared the cache, but the context menu was still rendering.

Well, I was AFK for an hour or so and when I cam back and refreshed the screen, I received a "Failed to load menu!" error, which makes sense. So, I copied the Default.XML file back to the folder and now it renders a context menu closer to what I am looking for using the XML you provided. Thanks!
