pfBlockerNG not showing the correct sub interfaces for IPv6 in the logs

[lou1z]

Hi,
I have pfBlockerNG up and running and blocking ads IP's etc. It is filtering on IPv4 & IPv6.
However when I look at the DNSBL logs, all IPv4 sources come from the correct sub interfaces eg LAN0.10, LAN0.11 LAN0.12. All is well.

The parent interface LAN0 is unassigned in pfsense with no config etc.

So, I have pfBlockerNG filtering IPv6 addresses which is shows in the logs. However, all IPv6 addresses are logged as coming from interface LAN0 (which is unassigned)
It doesn't matter what IPv6 address range it comes from eg LAN0.10 subnets, LAN0.11 subnets etc. It all shows as source LAN.

I've gone through all of the config but can't see where the issue is occuring.
Any pointers would be appreciated. Thank you.
