Where is the event cleanup option?

Where is the event cleanup option?

We recently brought up the ADAudit Plus, and was wondering the retention of the events collected on the server?
Can this be modified?

The instruction indicated an "event cleanup" option, but there is no where to be found. We only see an option for "Archive Events".

The version and build we deployed is:
Version 4.6.0 Build 4691
