What is the issue you’re encountering

What steps have you taken to resolve the issue?

Tried deleting and creating again. Changed TTL. They are set to DNS only without an option to change.

What feature, service or problem is this related to?

DNS records

Works from Cloudflare’s side:

learn.ciberspring.com.  60      IN      NS      ns1.exacttarget.com.
learn.ciberspring.com.  60      IN      NS      ns2.exacttarget.com.
learn.ciberspring.com.  60      IN      NS      ns3.exacttarget.com.
learn.ciberspring.com.  60      IN      NS      ns4.exacttarget.com.

Same explanation as here as for why you can’t see that with DNS checkers.
