Deleted Report Schedule won't stop emailing

I was testing how to use the Report module and created a daily report to be emailed to me through the Report Scheduler. I left it for a few days and it worked perfectly. Reports were emailed to me on time every day. However, I have since deleted that report schedule but continue to receive report emails everyday. I can't seem to turn it off. I have checked my report scheduler and it says "No Reports Scheduled". How do I get this to stop emailing me?

I was going to use this feature to email various people. But now I'm concerned I won't be able to stop reports even after I delete the schedule.
