FG-61F: "FortiSwitch Ports" does not show devices anymore in column "Device Information"

[dan]

FG-61F, 6.4.5, several FortiSwitches connected via FortiLink.

Since today, the FortiSwitch Ports view does not show anymore any devices in the "Device information" column.

The "Device inventory" in the Web GUI (Dashboard, User&Devices) is empty as well.

Yet, if I check the device database with the CLI command

diag user device list

I can see that all devices are apparently still in the DB.

I like the device information in the GUI. How can I get that information back?

Interesting side info:

diag user device clear     <---  seems not to work at all...

fortipg # diag user device stats generation.global 509997 generation.seen 69192 generation.deletion 44 count 139 joined 0 create_failed 0 fd 5 hash 2048

Regards

Upgraded to 7.2.3 and the problem is still there.

After a couple of hours the device list goes empty.

This was one of the best features of fortigate's user interface... 

please fortinet, fix this!!

Upgraded to 7.2.4 and the problem is still there as well.

"diag test app wad 98" no longer clears it.
