Ok, firstly, there is no second "g" in "bug". Secondly, you should ask your question in the Skyrim section of the forums, as Dragonborn is DLC for Skyrim and not Morrowind (which is the section you're posting in).

As for your issue, make sure you haven't left the cube in any of the other slots around the area. You may have left one somewhere.
