(This is about the apple-looking dock, not the tabbed dock, not sure what to call it)

Using Windows 8.1

I have an application that I am currently running.  The icon for this application shows up in the slider dock at the bottom.  When I right click any icon on this bar I get the option "remove icon" except for this one.

Dragging the icon up and out of the dock I get a prompt "are you sure you want to remove this shortcut" with a remove and cancel button.  When I click remove I get a little puff of animated smoke but the icon stays right where it was.  As soon as I close the application the icon will finally vanish.

Along the same lines, when I rename a shortcut in the tabbed dock the name change is not reflected until after I switch to a different tab and back again.  Name changes should take place immediately and refresh.
