Unbound is all good here, you're expecting too much from
"nslookup". Unbound returns the correct answers, but "nslookup" fails to
ask the wanted questions to Unbound (and does not show the DNS

Please try to use the tools "dig" or "drill" to send the query to
Unbound, the output will either give you a clue or, if posted here, will
give the participants of this mailing list an idea what might be wrong.

Example (using my local Unbound instance):

% dig 

; <<>> DiG 9.10.0-P1 <<>>
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 42320
;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 1

; EDNS: version: 0, flags:; udp: 4096
; IN      A

;; ANSWER SECTION: 900 IN   A 900 IN   A
