Managed fortiswitch, device information

So I’ve got some switches connected through the fortilink but not using nac or dynamic vlans, just good old standard vlan 100 for phones or 200 for desktops ect…
When you go to fortiswitch ports you see a whole bunch of information relating to all the ports on the managed switch. I’m interested in the device information tab which shows you info like ip and mac of the desktop or phone connected.
I’ve set the Mac aging interval to 0 however when a port goes offline let’s say because of a layer 1 issue the device information seems to be persistent and I can’t find a way to clear it or get it to dynamically clear down when that device is no longer connected.

Does anyone know the global or managed switch setting I need to apply to get this to happen?

Thanks in advance
