Delete "empty" level

How can I delete a level that is supposed to be empty? In the attached image in the Level Display I have lvl 1 Control "bold" with no elements. In the Level Manager level 1 has a Shared Cell Def under "type", in the element count there is no count for cell, cell header or shared cell instance. I have used selectby attributes and have found no shared cells or cells so I am unable to delete the level or delete elements in the level.

Any ideas?

Thanks
