usermanager active sessions and active users not available

Hello everyone.
I had a perfectly working usermanager on RB1100.
Then 5 days ago the usermanager stopped showing the number of active sessions and active users. I can actually see from winbox ip-hotspot-active that there are active sessions using usernames and passwords given by the usermanager but inside the user manager it keeps saying 0 active sessions or users.

The only things I remember touching before this issue was the idle time out as well as resetting the counters on usermanager.

What could be the reason for this new behaviour.

Exactly the same here…
After clear database…no sessions or users shown active in the user manager…
any suggestion?

version 5.4 running on X86

thanks in advance
