ORA-39181: Only partial table data may be exported due to fine grain access control on "OWNER"."TABLE_NAME"

As the errors points that this is the issue with the fine grain access on the table. User surprisingly user system need exemption and can be done by

 GRANT EXEMPT ACCESS POLICY to System;

Next time you perform the export using system it should be all good.
