Mod_security logdata parameter

#1
Using Comodo Litespeed rules I can't make Litespeed log "logdata" messages. This log param is used to diagnose why the rule is triggered.
I was researching a little but wasn't able to find any mod_security specific option related to this log param. Maybe "SecAuditLogParts" is related to this issue but Comodo Litespeed WAF does not contain any "SecAuditLogParts" setting. Here is a link to Comodo forum how users report false positives including "logdata" log.

Sample rule:
Code:
SecRule ARGS|ARGS_NAMES|REQUEST_COOKIES|REQUEST_COOKIES_NAMES|XML:/*|!ARGS:/body/|!ARGS:/content/|!ARGS:commentText|!ARGS:desc|!ARGS:/description/|!ARGS:introeditor[text]|!ARGS:_signature|!ARGS:Post|!ARGS:html_message|!ARGS:text|!REQUEST_COOKIES:/__utm/|!REQUEST_COOKIES:/_pk_ref/ "(asfunction|data|javascript|livescript|mocha|vbscript):" \
    "id:212770,msg:'COMODO WAF: XSS Attack Detected',phase:2,capture,block,setvar:'tx.xss_points=+%{tx.points_limit4}',setvar:'tx.points=+%{tx.points_limit4}',logdata:'Matched Data: %{TX.0} found within %{MATCHED_VAR_NAME}: %{MATCHED_VAR}',t:none,t:htmlEntityDecode,t:lowercase,t:removeNulls,t:removeWhitespace,rev:5,severity:2,tag:'CWAF',tag:'XSS'"

Please upgrade to the latest build of 5.1.17, it may take care of this problem.
Already tried with 5.1.17 (b2), it's same.
Here how the log line looks like.
Code:
[Wed Jul  5 13:16:45 2017] [error] [client 123.123.123.123] ModSecurity: Access denied with code 403, [Rule: 'ARGS|ARGS_NAMES|REQUEST_COOKIES|REQUEST_COOKIES_NAMES|XML:/*|!ARGS:/body/|!ARGS:/content/|!ARGS:commentText|!ARGS:desc|!ARGS:/description/|!ARGS:introeditor[text]|!ARGS:_signature|!ARGS:Post|!ARGS:html_message|!ARGS:text|!REQUEST_COOKIES:/__utm/|!REQUEST_COOKIES:/_pk_ref/' '(asfunction|data|javascript|livescript|mocha|vbscript):'] [id "212770"] [msg "COMODO WAF: XSS Attack Detected"]
