TOPIC: System Message after payment wi PayPal

TWO system notifications appear after a payment has been made thru PayPal. Message "You have successfully made your payment". Notice "Message body empty".

Where is that "notice" coming from? PayPal? I am not seeing anything in DT Register configuration or the Pay Option to write a message.

What version of DT Register and Joomla?

Installed Version: 3.1.8b for DT Register
Joomla 3.5.1

First, update to DT Register 3.1.9. If the issue remains, it's definitely a setup issue. In configuration of DT Register, make sure:

1) Emails tab has "From Name", "From Email" and a message body and subject for "Thanks Email" and "Admin Notification Email".

2) Messages tab has content for "Thanks Message".

3) Within each event, you also have an Email and Messages tab where you can enable custom messages and emails that override those setup in configuration. Make sure everything is set correctly IF you have custom elements enabled. Maybe you have enabled a custom message but not actually set one up.

Uploaded newest DT Register
1. Emails tab has from name and email and message body in all
2. Message tab has messages entered for everything
3. Custom message is enable and messages are in place.
Now what? changed time to 3:00 pm, it's 2:36 and register button is still available and letting me sign up.

Sorry #3 about time is on another topic issue.
Looking at the event under messages, I see that there is NO message set up for Thank You Message Onscreen or redirect. It is checked No to enable however there are options "Redirect to URL" & "Display Onscreen Message" and the Display onscreen message IS selected? Would this be why?
