BiteSMS - Group SMS

New BiteSMS user here and I have a quick question.

When I receive a group sms and the quick reply pop-up comes up, when I reply it's only sending it to the person I received the sms from and not to everyone else. Is there a setting I need to tweak in order to get this working like the default sms app? It would be nice if the quick-reply would actually send the sms to everyone instead the person I got the sms from.
