Log&Report with disk: No entries for "Forward Traffic"

Hello,

- We´re running FortiOS 7.4 on FortiGate 601E (with hard drive)
- After upgrading to FortiOS 7.4, there were no more entries within the GUI @ Log & Report => Forward Traffic
- For "Log location" "Disk" is set in GUI

Of course Disk logging is still enabled, i.e.

config vdom
edit vdom two

show full-configuration log disk filter
config log disk filter
set severity information
set forward-traffic enable
set local-traffic enable
set multicast-traffic enable
set sniffer-traffic enable
set ztna-traffic enable
set anomaly enable
set voip enable
set dlp-archive enable
set forti-switch enable
end

config log setting
set fwpolicy-implicit-log enable
set fwpolicy6-implicit-log enable
set extended-log enable
set local-in-allow enable
set local-in-deny-unicast enable
set local-in-deny-broadcast enable
end

config firewall policy
edit 2
set logtraffic all
set logtraffic-start enable

Am I missing any additional parameter?
