Gontroda Núñez - Connection questions?

I am curious as to why Gontroda Nunez has Munio Velaz II and Velasquita Sanchez listed as her parents. According to every source I have read, Munio and Velasquita only had 4 children: Aznar, Lope, Sancho, and Velasquita.

Secondly resources show that Asur Fernandez and Gontroda Nunez had 5 children: Fernando, Oveco, Muño, Nuño, Gutierre, Gonzalo, and Teresa.
Teresa was the only daughter and she married Sancho I, and was the mother of Ramiro III.

Suggestions based on Onomaticsare not sufficient proof of parentage, especially considering if true, Velasquita was not her mother. Please detach these familial connections as they are inconsistent.
