Unable to add A record

I am unable to add A record to my domain in Netlify DNS panel

I get this error

A: 400 - link exists, all config must be empty.

Can some one please help me out

Is there an existing NETLIFY/NETLIFYv6 type system record already in place for the same domain name? If so, our support staff can delete the “system” record which will allow the new record to be created.

There a similar question about this here:

​Please let us know if this is the case and, either way, what the domain name affected is. We’ll be able to delete the system records.

If there is no system record or there are other questions, please let us know this as well.

Thanks for the reply.

Can you please help me delete the system records for the below domains

  1. hatkits.xyz
  2. hatkit.xyz
  3. hatkits1.xyz
  4. hatkit.club

As far as I can see, we host only hatkit.xyz in your account. I can remove the records there. Do you want me to put a different value in place when I do? Otherwise your site will be offline.

The other domain (hatkit.club) belongs to a different customer so I cannot remove it based on your request.
