This happens when Team Approach has a single code with different descriptions depending on context.

For example, in Team Approach MO, could stand for "Mother" in the "Mother to Son" relationship but "Member Organization" in the "Member Organization to Board Member relationship.

Blackbaud CRM does not allow this, so the Team Approach relationship types will need to be fixed in order to sync successfully.

You can use the following query to identify the records in Team Approach that must be updated.

For example:
SELECT * FROM   RELATIONSHIP_TYPE
WHERE  RELATIONSHIP_TYPE LIKE '%/{dupe code}';

The field to update is Long_Decription on the Team Approach relationship.
