The containing zone is dla.mil, with no delegation for this
subdomain.  Its SOA is:

    dla.mil. IN SOA eagleib1.ad.dla.mil. gregory.weaver at dla.mil. 2008266450 10800 1080 604800 900

I am reporting the "rname" as an email address with a "@" between the
first and remaining labels.  So perhaps start there.

Somehow the subdomain as served by the parent's nameservers ended up
with its own separate DNSKEYs and a DS RRset owned by the subdomain,
rather than the parent:

    gtm-ext.dla.mil. IN DNSKEY 257 3 8 AwEAAakiB93xx2GkyKCjqE9tsGE8Xb/cbS9oW+AIjD23bvsRxRVczDUchMbw6RvbJq/qH9rdspXCStgpdEvLWXWC0cCTkx/cJ8hf3UJMgMj3jd3lTxSo1KJaS5DXRdJR2+OuYEUZ3NMVJZhuJsVlYDJRFWOrnLOxuWYU65aY/eRE7rp9Z9aPN21bIDzokmVI9L3v8hd3ApQJhe2B4hnuKvvU5R+0lDkK9t2cHjvrh3ggAhR9fqZIUkVWzZA01mgJR3D8gt1MiwX9sPGwSAmCHCGdljrhvPy675CBt3cSdhCced1Ys4eIzblyp/fWsdRGaldYWWZYQUw21NGzCVTd0faNSpc=

So sure looks like some delegation data is populated in error into the
subdomain rather than the parent, but on the other hand there is neither
an SOA RRSet nor an NS RRSet for the subdomain...
