That's right, I already wrote this in my previous post - every user who has access to this option only sees what they have reported in the past 30 days. This is designed to give us insight only into recent reports, and not into the overall report history which becomes irrelevant over time. It also makes sense, because if something is not handled in the first 30 days after the report, it is almost certain that it will remain unhandled forever, the same as reports marked as bad.
