Where is the Access Policy >> Reports: Preferences menu? IN APM 12.1.0

I would like to confirm the save date of the Event Log in F5 APM 12.1.0.

 

It is estimated to be about 6 months, but sure information is needed.

How long can I see the reports in the Event Logs?

 

There is no related Sol document, it seems like it could be set in Reports: Preferences, but it is gone. In version 12.1.0

 

Please help me.
