Ayuda con una view

[skat]

Buenas, a ver si me podeis ayudar con una view de tipo taxonomía. Vereis he creado un vocabulario con varios términos y algunos son padres de otros. Lo que quiero es crear una view de que sea de la siguiente manera:

Elemento padre1
Elemento hijo1,elemento hijo2,...

Elemento padre2
Elemento hijo1,elemento hijo2,...
.
.
.

Para hacerlo, lo que he hecho ha sido: crear una view tipo taxonomía, en relaciones he elegido taxonomía:parent term, en fields he puesto dos: taxonomía term y marco la relacion parent term y exclude from display, y taxonomía term otra vez pero en este caso no marco que se requiera la relación.

El tema es que casi me sale pero el los términos padres me salen repetidos, alguien me podría echar una mano??

copio el código de la view:
