It's probably in there to fill in the gaps. For example, if someone had 5 good reports, 3 unhandled, and 2 bad in the past year, but the unhandled reports weren't visible someone would be wondering why the stats don't match up. So, it just showed 5 good reports, and 2 bad, but the user can see they have 5 total reports it might lead to confusion.
Yes, and a simple message could help
For example :
-snip-, 14 bad, 12 unhandled in the last three days /If the score doesn't match up then it's related to the old unhandled reports).
