The issue is covered at Can't set nameservers - (Inconsistent Set of NS / Nameserver not authoritative)
Right now it seems Cloudflare does not know about these domains at all. Adding them should be possible.
Is chin.ns.cloudflare.com one of the nameservers listed on the account for that 01trade address?
Could you also post the response you got from support? They really shouldn’t refer you to the forum.
