Upgrade from 1.0.1-SNAPSHOT-03-08-2007 to 1.2-BETA-1 - pfctl syntax error

[hsiang]

I just upgrade my secondary pfsense from 1.0.1-SNAPSHOT-03-08-2007 to 1.2-BETA-1.

After reboot i am getting these alerts:
[filter_load]: there were error(s) loading the rules: /tmp/rules.debug:408: syntax error pfctl syntax error in config file: pf rules not loaded. The line in question reads [408] pass in log quick on $WAN proto tcp from any to {a.b.c.d} port=252 flags S/SA ( tcp.established 90  )  label "USER_RULE: Allow Incoming SMTP Traffic"

I compare the files (tmp/rules.debug) with the master server i found there is additional line "(tcp.established 90)". i delete the line. however after reboot, it will appear back.

May i know where i can make a permanent modification? is it a bug?

My plan is to update the secondary server before update my master server. kindly advise.

Regards
Hsiang
