OpenVPN GUI log doesn't display old messages

[shshs]

Hi guys,

I'm curious why "StatusSystem->Logs->OpenVPN" doesn't display old messages but only for 2 days? I have quite large Log Rotation Size settings and the log entries that I'm looking for I can find in /var/log/openvpn.log file but GUI doesn't display it for some reason. I tried to filter logs by Time, Quantity... all fields, but GUI doesn't return anything on my requests, though actual log file (openvpn.log) contains these messages. Logs for all other processes like firewall. Thank you for your response.

I use the latest CE release:
2.6.0-RELEASE (amd64)
