Duplicate Billing Alerts Keep Appearing in Protected Content

Hello,

I ran a couple tests of the Protected Content plugin to make sure the payment gateways and everything else worked. It all seems to be working, however I keep getting duplicate alerts in Admin for the Billing page of Protected Content. Both test accounts have been paid, but they appear again as "Billed". I will delete these, and then they appear again.

Screenshot is attached.

Thanks,
Chris
