Auto Filter Reload causing weird error

[ohiosemi]

The twice a day auto filter reload is throwing an error

There were error(s) loading the rules: /tmp/rules.debug:376: syntax error - The line in question reads [376]: pass out route-to ( em0 X.Y.Z.33 ) from X.Y.Z.36 to !/ tracker 1000011161 keep state allow-opts label "let out anything from firewall host itself"

When I check the /tmp/rules.debug file at line 376, the rule is different:

pass out  route-to ( em0 X.Y.Z.33 ) from X.Y.Z.36 to !X.Y.Z.32/29 tracker 1000011161 keep state allow-opts label "let out anything from firewall host itself"

I don't know why the destination network isn't there in the error messages, but does exist in the file.

A manual filter reload doesn't cause the same error.

Current Setup: Dual WAN with failover, multiple virtual IPs on both, internal VLANs

Any ideas?
