I've acquired a bunch of junk clients, farms and flag names from accidental imports from buying used tractors and not getting them cleared before hooking to op center, and sometimes doing custom work and accidently they give you all of the setup data.  They only show up when trying to filter data in the "Land" tab.  
There is also hundreds of flags from others that has the same problem.  They are not active and even if I delete them they don't leave.
Any ideas?
