Hello,I'm having a problem with advanced filtering of tickets. Most of the criteria and also multiple criteria are working fine. But when comes to advanced filtering with check boxes, after a check box in advanced filter is checked or unchecked and applied there is no change in filter result even the values are set in tickets.What can cause this?Thank you.Server InformationosTicket Version v1.9.8.1 (4752178)Web Server Software Apache/2.2.15 (CentOS)MySQL Version 5.1.73PHP Version 5.3.3PHP Extensions - all OKPHP Settings - all OK
