I wanted to provide a follow-up to this issue.  I have cleared all cache in my browser and also used alternative browsers.  I have only had Quickbooks send one reminder on its own since i posted this question otherwise I have had to send reminders manually and even when I send them manually they do not always get sent.  I have had to go in to my own email and manually forward each invoice that is overdue. 

If anyone has any assistance it would be greatly appreciated.
