Cannot Delete MA - The image or delta doesn't have an Anchor

I have an Export only ECMA 2 management that provisions data to an external data source via a web service.  During testing I ran into an issue where a full sync on the authoritative data source (a SQL MA) caused the error 'The image or delta doesn't have an Anchor'.  The error has persisted after

- Doing a full import/full sync on the authoritative data source

- Deleting the content of all MA's

- Ensure that the latest hotfix has been applied to the Sync Service

- Clearing the content in the mms_metaverse, mms_csmv_link and mms_connectorspace tables

I can still see the record that is causing the issue in the MV and apparently it still has a connector to the ECMA 2 mgmt agent.  However, I cannot remove the connector on account of the error.  If I try to delete the MA I get the same error.  Any suggestions on how I can resolve this issue?

Thanks
