TF26027 error after work item import

I created a custom work item type and uploaded it to 4 Team Projects.
On 3 of these Team Projects all seems to be working fine.  On the 4th Team Project, when I click 'My Work Items' query I get an error showing "TF26027: A field definition somefield in the work item type definition file does not exist.  Add a definition for this field, or remove the reference and try again."

Please note this was the exact same work item uploaded to all projects, but only one complains.

I ran witfields, and verified that the field it complains about does not exist.  I also verified that there are NO references to this field in the work item type that I uploaded.

Anyone have any ideas   I would relly like to get this fixed soon as we just converted all of our old bug tracking over to Team, and the project that is complaining is our main project -- most developers are using it.

Thanks in advance.
