Delete shared cell def

I am trying to clean up A LOT of dgn files that have junk on the DEFAULT level.

I have tried to delete elements on the level and move the elements to another level using the key-in(s) level element deletd default, level element move dest:60 Default

Sometimes the message center indicates something was moved but when I check level manager I still have a shared cell def(s). I have tried delete scdefs all but the shared cell def remains.

Is there something I am missing?

Thanks for ANY help!
