The .nl ccTLD has multiple servers:

If you want to check out a particular zone, the best thing to do
is run standard DNS debugging tools like "doc", "dnswalk", and/or DNS
Expert Professional.
The latest version of doc says:
% doc -d auto-matic.nl
Doc-2.2.2: doc -d auto-matic.nl

Clearly, you've got some problems you need to get worked out with
the owners of nxs.nl and zoneedit.com. There's two different
versions of your zone out there, and they disagree. Until you get
the delegation issues corrected, nothing else is likely to work right.
