AWS Route53 Private Hosted Zone. NameServers being deleted

[alexandrenakagawa]

NOTE: Have a general question? You'll get a better response on the dnscontrol-discuss email list!

Describe the bug
If you create a private hosted zone on aws Route53, and try to use with dnscontrol, the NameServers associated with the zone are deleted when do a preview or push

To Reproduce
Steps to reproduce the behavior:

1. Create a private hosted zone on route53.
2. create a simple dnsconfig.js with
   var REG_NONE = NewRegistrar("none");
   var DSP_R53 = NewDnsProvider("r53_main");
   D("domain.local", REG_NONE,
   DnsProvider(DSP_R53),
   A("teste", "2.2.2.2"),
   A("teste2", "2.2.2.2")
   );
3. Do a preview or push.
4. CONCURRENTLY gathering 1 zone(s)
   SERIALLY gathering 0 zone(s)
   Waiting for concurrent gathering(s) to complete...DONE
   ******************** Domain: domain.local
   4 corrections (r53_main)

• DELETE domain.local NS ns-0.awsdns-00.com. ttl=300
• DELETE domain.local NS ns-1024.awsdns-00.org. ttl=300
• DELETE domain.local NS ns-1536.awsdns-00.co.uk. ttl=300
• DELETE domain.local NS ns-512.awsdns-00.net. ttl=300
  INFO#1: No nameservers declared for domain "domain.local"; skipping registrar. Add {no_ns:'true'} to force
  Done. 4 corrections.

Expected behavior
Expected behavior is a no change in NS. DNSControl reads the NameServers from zone and normalize
Works if the zone is a Public Hosted Zone

DNS Provider

• r53_main

Additional context
Error occur only with private zone
used DnsProvider(DSP_R53, 4), or DnsProvider(DSP_R53), in config and got same error.
tried to declare R53_ZONE("XXXXXXXX") and got error too.
