Invoice Not Clearing in Reminders

Storageinasnapp

I have one tenant whose invoice will not clear in the reminders section.  
I have emailed it to her, verified email was delivered
I have even printed out the invoice, however, the invoice still shows up in "Reminders" as needing to be sent.

Anyone have this happen to them?
Any idea how I can fix this?

All other tenants invoices Print or Email and clear out of Reminders.:/

Better call SiteLink, that's odd. Also maybe try disabling it for a month (remind yourself to send it manually) then enable it again, see if that resets it.
