Log fortigate

Hy !

I have a problem with the number of recording report logs.

In my fortigate machine I have only nine summary report. (from log reports -> report)

In Logging and Archiving settings i have the option selected Memory and Send Logs to FortiCloud

Event Logging has all the options selected

Display Logs From are selected from Memory

My question is ...What can i do to have all the summary report in my fortigate machine ? (last 30 days)
