I think the problem is that your two servers return different
answers to the same question:

That result matches the two zone files you show, with same SOA serial
number but different content. The comment in the SOA record indicates
that you don't slave the zone to ns2 and instead edit two distinct zone
files.

Either sync the zone files or set up the second server as slave and you
should be fine. You can check with DeNIC's pre-delegation test here:
