Fortigate Forword Traffic device name

Hello everyone, I'm writing to ask you something.

If you look at Fortigate's Forword Traffic -> device
Some logs show the device name correctly
Some other logs do not display the device name properly.

I posted something similar before, but I don't think it worked out well, so I'm writing it again.

Please let me know what items I should check.

And I'm guessing, but I'd like to ask if it's related to the issue that you didn't activate the device detect function.

Thank you
