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.
