Reporting Emails being sent every hour

I’m using the plugin with your reporting addon. I’ve get it configured to send an email summary with the logins weekly. However, we are getting emails sent every hour.

The header of the HTML report is showing a date span of Start Date 01-01-1970, End Date 01-01-1970.

I only have the one email report configured, and we are only getting the one email notification sent, it is just coming every hour.

Can you help me troubleshoot it?
