Looks like a bug.  It is still there, but for some reason, when you select a new layer, it places the rectangle in the background of the image in front of the bulletin board image.  Delete the rectangle from the base layer or move it to a spot where it hangs over the edge of the rectangle, and you'll notice it still displays the bulletin board.

As a workaround, I suggest creating a master slide for your background objects.
