Conflicting Nameservers

I just signed up. I read that I need to set the nameservers at my registrar to (ns2, ns3, ns4) which I did. My new account was created but on the sidebar the nameservers listed for the FTP are (ns2).

Which nameservers should I be using for my registrar, the byet one or the ebizy one?

Either one works, both sets of nameserver addresses point to the same physical servers.
