HI, we are having trouble getting the Original Referrer field to sync to it's counterpart in Salesforce. We followed the process outlined in the support docs to create the field in SFDC, and it was supposed to populate automatically, but something went wrong. In the aftermath, I think we tried deleting the SFDC field and creating a new Original Referrer field, but that won't sync either. I think we need to start over somehow, but we're not able to delete or reset the Orig Referrer fields in Marketo. What's the best way to proceed?
