In .dgnlib there is a level 0 and show not used. will not delete in looking further Using properties the Usage tab shows type Shared Cell Def Id REV_1_1  I tried the file compress, after that closed and re-opened

same problem. I am out of what to do BTW this was a level 56 I could not delete so I made Level 0 and remapped then deleted Level 0
