At last look LSWS writes out the 'mod_security' records slightly differently than actual mod_security. This causes CSF to not parse/pick up the LSWS mod_security log records. I can post more details if necessary.
Do the new versions for you pick up everything? I'm trying to rule out if it's our rules causing nothing to show up in logs or if it's more bugs as far as LSWS mod_security functionality replication.
