Fortinet Fortigate 61E not logging even if all available logs options are active

Hi, i'm working on a Fortigate 61E, and even if the disk is 99.9% empty and all the options for local logging (via GUI) are active, It does not log anyway, it only lets me see the "live monitoring" logs but the hardware events and all the rest no ... I do not know how to proceed, could you help me? Thank you so much
