Error in CNAME resolving.

[ufm]

RFC1034 says in 3.6.2:

CNAME RRs cause special action in DNS software.  When a name server
fails to find a desired RR in the resource set associated with the
domain name, it checks to see if the resource set consists of a CNAME
record with a matching class.  If so, the name server includes the CNAME
record in the response and restarts the query at the domain name
specified in the data field of the CNAME record.

but Alfis does not return even cname. For example:

dig -t CNAME _acme-challenge.cc.ygg @302:db60::53 

; <<>> DiG 9.18.12-0ubuntu0.22.04.1-Ubuntu <<>> -t CNAME _acme-challenge.cc.ygg @302:db60::53
;; global options: +cmd
;; Got answer:

_acme-challenge.cc.ygg. 3600    IN  CNAME   9c76e0cb-19eb-4890-8da8-52e49950ed06.auth.acme-dns.io.

I.e. _acme-challenge.cc.ygg have cname record. But when ask TXT, for example:

ig -t TXT _acme-challenge.cc.ygg @302:db60::53 

; <<>> DiG 9.18.12-0ubuntu0.22.04.1-Ubuntu <<>> -t TXT _acme-challenge.cc.ygg @302:db60::53

But at least it should be:

;; ANSWER SECTION:
_acme-challenge.cc.ygg. 3600    IN  CNAME   9c76e0cb-19eb-4890-8da8-52e49950ed06.auth.acme-dns.io.

and correct answer is:

;; ANSWER SECTION:
_acme-challenge.cc.ygg. 3600    IN  CNAME   9c76e0cb-19eb-4890-8da8-52e49950ed06.auth.acme-dns.io.
9c76e0cb-19eb-4890-8da8-52e49950ed06.auth.acme-dns.io. 1 IN TXT "tAOc2yS8KqyEqqpt2GGEXQ9cTSbvD9sdnNdGegJC7Jk"
