Benedict de Cornouaille, Count & Bishop of Cornouaille, Bishop of Quimper - Question About Connections

According to this site, the Benedict / Benoit who was married to Guigoëdon de Vannes was the son of Budic, not his grandson:

https://fr.wikipedia.org/wiki/Beno%C3%AEt_(comte_et_%C3%A9v%C3%AAqu...

If what is on that site is correct, it seems an extra generation has been added between this Benedict and Budic. Or maybe I'm just following iit wrong.

Any assistance to clarify the connections would be appreciated.
