Domain is reporting incorrect Name Server information
Focusing on the actual problem with your domains:
Following the chain of delegations for lamardesigngroup.com
you'll see a delegation to ns1.lamardesigngroup.com
and ns2.lamardesigngroup.com
with glue referring to 212.1.213.8
.
lamardesigngroup.com. 172800 IN NS ns1.lamardesigngroup.com.
lamardesigngroup.com. 172800 IN NS ns2.lamardesigngroup.com.
ns1.lamardesigngroup.com. 172800 IN A 212.1.213.8
ns2.lamardesigngroup.com. 172800 IN A 212.1.213.8
However, the authoritative records served by 212.1.213.8
are:
lamardesigngroup.com. 86400 IN NS ns2.lamardesigngroup.com.
lamardesigngroup.com. 86400 IN NS ns1.lamardesigngroup.com.
ns1.lamardesigngroup.com. 14400 IN A 198.20.251.113
ns2.lamardesigngroup.com. 14400 IN A 198.20.251.114
There's clearly an inconsistency between the glue and authoritative address records for the nameserver names, leading to different addresses being used in different situations.
This in turn also affects your other domains that use ns1.lamardesigngroup.com
and ns2.lamardesigngroup.com
as nameservers.
