Issues serving one specific unbound local-zone record

[shadyproject]

I have set up AGH alongside an unbound installation. Unbound is listening on localhost only, with AGH listening on the ethernet interface and forwarding everything to unbound. AGH is configured with 127.0.0.1:53 as the upstream DNS server, the Bootstrap DNS server, and private reverse DNS server. All but one of the records are returning correctly. The record that is not returning correctly is the record for the host itself running AGH, which returns 127.0.0.1 when queried through AGH, but returns the correct value when queried through unbound directly. Any ideas as to why that might be?

Response when querying unbound:

dig agh.home.mydomain.com @127.0.0.1

The host record is configured in unbound exactly the same as other domain records, but is the only one for which this happens.
