[Snort-users] Something is wrong with snort logging?

I have a snort rule:
alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:"Custom Likely
Successful Generic Phish 2016-09-23"; flow:to_server,established;
content:"POST"; http_method; content:".php"; http_uri;
content:"clntnetid="; depth:10; fast_pattern; http_client_body;
content:"&pword="; distance:0; classtype:trojan-activity; sid:10001030;
The following event shouldn't trigger without a "clntnetid" in the string
looks like some data isn't getting logged into the snort tables:
[1:10001030:1] Custom Likely Successful Generic Phish 2016-09-23
2016-11-07 04:26:06.103000-05:00 188.8.131.52:54862 <http://184.108.40.206:54862/>
-> 220.127.116.11:80 <http://18.104.22.168/>
TCP: Data Triggering Snort Rule: POST /wp-admin/css/wep-et.php
143::~~Connection: keep-alive::~~Accept: text/h
Mozilla/5.0 (iPhone; CPU iPhone OS 8_3 like Mac OS X)

en-us::~~DNT: 1::~~Accept-Encoding: gzip, deflate::~~::~~
Other event that triggered this alert had "clntnetid" in the data string.
Not sure if the events that are triggering this alert are having that
string in data and snort is not logging it in database, or something is not
correct with the rule that is causing it to trigger for the events NOT
having that particular string in the data.
Snort version - 22.214.171.124
barnyard version - 2-1.9
pulledpork - 0.7.0
Did anyone knows what might be going on?
