usermanager report doesn't show all sessions

Hi, we are an Italian Wisp working with mk for 5+ years.

We have an issue with usermanager, ros v5.26 on x86:
usermanager report doesn’t show all sessions recorded!

We have to send report to our customer, but: if we look at session history, it’s all fine, and we can see all navigation data. When we generate the report, some sessions - apparently randomly - are not showned. We tried all possible combinations for report.
At the moment we had to export session through cli, import in a spreadsheet e manipulate data using vba scripts…

Tell us if you need more information, any suggestion is appreciate.

Thank you, regards,
Vincenzo

I’m also Italian WISP from 7 year @ October, and I use user-manager 6.18 on x86.

I think is the time you upgrade routeros…
