Reproducing the Issue
Click on Details of a field in any MDF object to view this property.
It is usually used if the Type of the field is either Picklist or Generic Object (GO). If nothing is used in this field, then by default the field value will display along with External Code. If we do not want to see External Codes and we want to see only the values (labels), fill up this field with the following pre-defined values.
displayGOWithoutExternalCode : For GOs
displayPickListWithoutExternalCode :For Picklists
