Domain doesn't save DNS with specific product

[Eduardo Martinez]

Hi everyone, 

I'm having an issue when I'm creating a new order. 

I select a product, then when I register a domain to this product this doesn't save the predetermined DNS. I have been trying to register the DNS via the Local API, but doesn't work too. The API gives me the following error:

Array
(
    [result] => error
    [message] => Registrar Error Message
    [error] => No nameservers are defined for the server this domain is assigned to. Please correct and try again.
)

This only occurs when I select a specific product, with the other products works good. 

Do you know why this is happen?

Regards.
Eduardo
