Nameserver records returned by the parent servers are:   ['']   [TTL=172800]   ['']   [TTL=172800] was kind enough to give us that information.

Looks like the A records (the GLUE) got from the parent zone check are 
different than the ones got from your nameservers. You have to make sure 
your parent server has the same NS records for your zone as you do.I 
detected some problems as follows:
For the parent reported: [''] and your 
nameservers reported: ['']
For the parent reported: [''] and your 
nameservers reported: ['']
