There's nothing to see here, it's just that the amount of monthly reports coming in is much more than what the active mods can handle because most of the cases are handled manually, they're not bots I never expected them to handle all monthly reported cases, most of my last month reports were left unhandled I guess mod didn't pick it up
This is hardly the true reason for so many unhandled.
It really depends on when the reports were made, and when the cutoff for the reporting period was. For example, if someone happened t make many reports shortly before the reporting cutoff, it is possible that the mods simply had not yet had time to handle the reports.
A useful piece of additional context would be of the ~1700 unhandled reports, how many were handled as of 48 hours after the reporting period ended.
