Fortiweb 7.25, Syslog only System Event

In the WAF I have a Syslog policy configured. The FortiWeb documentation indicates that regarding “Configuring log levels” (loglevels):      Syslog events have different severity levels, such as "info", "warning", and "error". You can configure FortiWeb to only send events of a specific level.  For system events, you'll generally want to select the "info" level or higher.   The levels are these below, in my configuration I have it configured as "Critical", which includes system events and so on, you can try leaving only the "Informational" ones, perhaps this way only the "system events" ones appear. ”, that is my doubt too, according to the level table, if I set the "Information" level, perhaps it would only give me "System Events" messages
