No worries:
calconditioner.com
calconditioner.de
calconditioner.es
Did I understand that well?
If so, the issue is that you didn’t disable DNSSEC at your domain registrar, before you changed name servers.
You can often find the DNSSEC related configuration around the place where you change name servers.
Otherwise, you need to get in touch with your domain registrar to get that sorted out.
Additionally, regarding the .ES domain:
calconditioner.es. 86400 IN NS ns1.dnstools.nl.
calconditioner.es. 86400 IN NS penny.ns.cloudflare.com.
calconditioner.es. 86400 IN NS mcgrory.ns.cloudflare.com.
You would either have to remove the Cloudflare ones (if you want to remove Cloudflare), or remove the ns1.dnstools.nl
one (if you want to use Cloudflare).
