Filter.log showing IPV6 addresses

[orangepeelbeef]

My filter.log file on a pfsense firewall running 1.2-RC4 is showing ipv6 addresses.  It subsequently is also showing ipv6 logs on the remote syslog server.  I have no devices that I am aware of that are using ipv6 and if there are any, they shouldn't be.  How can I get the logs to show the IPv4 addresses?  The web log viewer shows ipv4 addresses, but the filter.log shows ipv6.

Any ideas?

here's a sample from my log
