Superfluous name server listed at parent

[MSIHE]

Hi,
I´m getting DNS Delegation warning from my setup (see image)



My setup is mydomain.com > child-ns and i have two own nameservers by one ip (which works fine):
ns1.mydomain.com
ns2.mydomain.com

problem is my third nameserver which is difference domain and ip.
ns3.example.com

I also allow zone-transfers to secondary nameserver IP in bind9.

"you should update the parent to match the name servers at the child as soon as possible"
any fixes for this warning?

I think somehow i need to add that third nameserver in vesta?

Thanks for your answers,
Vesta Rocks!
