Delegation check failed

I didn't specify the IPs but it found them - that is to say when I input my first DNS server it automatically populated the IP address field.  This was on the iis.se site as I noted in my original post.

My read of "glue records" is that they are A records within a zone file for DNS servers that are part of the same domain as the zone being described.

Based on that my glue records in water.com zone file for domain water.com in zone file water.com do exist as shown in my original post:
dswadns1        IN A    12.44.84.213
dswadns2        IN A    12.44.84.214

Also it seems Glue records are only necessary for subdomains and I'm not using a subdomain here - I'm not trying to delegate to any subdomain.

So both my Registrar and I have things associating dswadns1.water.com with IP 12.44.84.213 and dswadns2.water.com with 12.44.84.214.   I'm still mystified as to what the delegation message is trying to tell me.

Additionally whois shows the correct IPs for the above name servers being returned by the Registrar.   My zone file has A records with the correct IPs as shown below.:

This is the www.zonecheck.fr checking tool?  Like it says quite clearly
in the instructions, where the nameservers are part of the domain being
checked then you need to give IP numbers too.  If you do that, then the
water.com domain passes the test albeit with a few warnings about
everything being on the same network segment / same AS number.

Yes, if you're checking a live domain correctly registered and with the
right glue records in place, then zonecheck can find your nameservers
without external prompting.  If you're trying to check an unregistered
domain, then zonecheck will definitely need those IP numbers.  That's
really all those messages are trying to tell you.

        Cheers,

        Matthew
