Filters not filtering

[rreyna]

I am the help desk specialist for my college and i use kayako to keep track of students phone calls, emails, walk ins....i have a report that i send every week to my supervisor telling her the amount of each individual issue we have. I set up customized fields in ticket submission on the staff side. They check off what the issue (add class, unknown username, etc.) was and what type of support it was (phone call, walk in, etc.) Then i set up filters such as ADD CLASS. When i click on this it gives me every ticket with this issue which i then count and add to my report; however my filters dont seem to be working. These past weeks were our busiest. It says that there was only one unknow username for the 14th of January, but when i go back to view our full list i see at least 7 if not more for the 14th. I have tried deleting it and creating it again. Any suggesstions?

Thanks!
