[Unbound-users] Local-data CNAME-Records seems not to work properly

I am facing the following problem:
We need to fake some CNAME-Records to test new deployments, mainly located at Amazon AWS. To do this, we have the following setup:
local-zone: "example.com" static
local-data: "www.example.com IN CNAME example-aws-dns-record-1234567.eu-west-1.elb.amazonaws.com."
local-data: "www2.example.com IN A 22.214.171.124"
Note that the CNAME points to a foreign domain and since it points towards a load balancer, which changes his IP quite often, we must use CNAME records.
When using tools like 'dig' everything works fine and the asked CNAME or A record is answered. We experience problems, when try to use the CNAME record in a 'normal' DNS request, like ping a DNS-Name.
ping www2.example.com works fine. www2.example.com is resolved to 126.96.36.199 and the IP receives a ping.
ping www.example.com<http://www.example.com> does not work at all -> "ping: unknown host www.example<http://www.example>.com"
-> it's almost like unbound would deny to resolve "example.com-1234567.eu-west-1.elb.amazonaws.com." (which by the way works finde when I directly ping this) when it has previously served the fake CNAME.
Can you help me to get rid of this very specific problem?
Thank you in advance,
