Testing out a registration form where the client wants to send a pdf invoice to the registrant with form details and payment instructions.  
From video instruction on youtube it says to put a shortcode in the email to link to pdf:
[frm-pdf view="1611" entry="[id]" public=1]
The email sends fine but when testing the link, I'm getting the incorrect information for another user's prior registration.  Searching documentation I could not find a reason why the other registrant's info would be pulled.
