Consulta me Genera Una Fila Vacía

[jpogsistem]

Que tal al hacer este select me salen los registros correctos + 1 fila Vacía con la única información de 0. No contacted

SELECT po.provider_name, po.provider_id, po.website, co.phone_code, po.city, po.country,
po.area_code, po.main_phone, po.unicef,substring(IFNULL(max(re.status_2),'0. No Contacted'), 1,100)
as status_2, po.manager
FROM remarks re RIGHT JOIN ( provider po RIGHT JOIN countries co ON (co.name=po.country AND po.country='Bolivia')) ON (re.provider_id=po.provider_id )
AND (po.manager='Pedro Perez') GROUP BY po.provider_id
