Logical and Physical topology in Fortiview

Hello

I'm working with a fortigate 60E, and I can't see all the logical and physical topology in the fortiview section.

I only can see the fortigate and a Windows10 machine connected to it. But I have in other interface a physical swicth (juniper) with 3 PLCs communicating with Windows10 machine without problem.

I neither could see my own laptop conected to an AP in the same switch.

Another thing is that i can't see the timeline in the fortiview section ( to choose 5min, 1h or 24h), but i think its because the fortigate 60E doesn't has a disk to log the events and it saves those in the memory, it could be the reason?

Thanks
