Cisco firewall and router are showing syslogs as below but not showing any data from the reports tab under network

select a date format:  [last 24 hours]

firewall is showing about:  180,000 messages

router is showing about 11,000 messages

dashboard is showing tables and graphs OK

during the morning I have logged onto both device with a failed attempt and successful logon

this is the bit that shows - "No Data Available"

goto reports tab

select Network Devices

scroll down and select Firewall Logon Reports

select logons and failed logons and both reports  - "No Data Available"

I've changed the date to be last 7 days / last 30 days and still nothing.

go into the logs and can see my failed logon attempt:

"User authentication failed: Uname: letmein"

one thing just sprung to mind was the logging level, currently set to notification, set to information and same issue

any suggestions ?
