I'm failing to reproduce the errors you see.
Checking the authoritative nameservers for `well.com` yields `23.22.72.90` for the A record and nothing for the AAAA
record:
% dig +trace NS well.com
...
well.com. 172800 IN NS ns-1103.awsdns-09.org.
well.com. 172800 IN NS ns-1783.awsdns-30.co.uk.
well.com. 172800 IN NS ns-459.awsdns-57.com.
well.com. 172800 IN NS ns-805.awsdns-36.net.
% for i in ns-1103.awsdns-09.org ns-1783.awsdns-30.co.uk ns-459.awsdns-57.com ns-805.awsdns-36.net; do dig @$i
+short A well.com; done
23.22.72.90
23.22.72.90
23.22.72.90
23.22.72.90
When querying Cloudflare's resolver, I get the same answer as what the authoritative servers return from where I am:
% dig @1.1.1.1 +short A well.com
23.22.72.90
And I can see that some third-party websites all show correct functionality, including what Cloudflare returns:
* https://dnsviz.net/d/well.com/dnssec/
* https://www.digwebinterface.com/?hostnames=well.com&type=A&useresolver=9.9.9.10&ns=all&nameservers=
We can continue off-list if you like.
