Surface Errors when opening or exporting data in Fluent

  I am trying to run a simulation that seems to have some old geometry defined inside fluent. I get the following type errors when setting up data exports:
  I saved everything and re-opened workbench from scratch then the solution:
  When it opens up I get a whole slew of errors:
  Preparing mesh for display...
  
  Error at host: zone-surface: invalid thread[2]
  
  Error at Node 0: zone-surface: invalid thread[2]
  
  Error at Node 1: zone-surface: invalid thread[2]
  
  Error at Node 2: zone-surface: invalid thread[2]
  
  Error at Node 3: zone-surface: invalid thread[2]
  
  Error at Node 4: zone-surface: invalid thread[2]
  
  Error at Node 5: zone-surface: invalid thread[2]
  
  Error at Node 6: zone-surface: invalid thread[2]
  
  Error at Node 7: zone-surface: invalid thread[2]
  
  Error: zone-surface: invalid thread[2]
  Error Object: #f
  
  I've tracked it back to stale surface definitions that exist from the previous geometry with multiple bodies that I swapped out. I have found where I can manage surfaces via the Surface->Manage menu where I can delete them manually. However some of my new surfaces use similar names and I can't tell which ones are the stale surface definition to delete. Is there a way to cause fluent to reload and repopulate the list of surfaces automatically?
  
  Can I delete all of them and somehow trigger existing ones to be re-created or loaded?
