Small issue on IP resolution to local DHCP lease in log view

[nekopep]

Hello,

I got my pfsense working perfectly with DNS resolver and DHCP server configured.
If I ping for example Router.mydomain.home -> I got the ip of the machine.
The DHCP lease view, list the IP + machine hostname so pfsense got all the information.

Now my issue is that when I take a look at firewall logs in:    Status/System Logs/Firewall/Normal View
I got some blocked IP that I want to debug.
If I click on "click to resolve" on a local IP pfsense can't manage to resolve it to for example router or router.mydomain.home.
Instead I get a "cannot resolve" message.

Please see screen capture.

Is this possible or any opton is missing in my config?
(Register DHCP leases in the DNS Resolver is active)

Thanks for your help!
