[Plugin: Exports and Reports] cron not working?

The daily cleanup of the reports is not working for me…the cron job is set up, but it is not deleting on a daily basis (neither the reports nor the rows in the db), plus I ran the cron job manually to double-check, but my reports are still not getting deleted.

If I Clear Exports Directory, the exports_reports_cleanup function is working properly. Any ideas what might be occurring?
