Papagayo help multiple voices

Hello. I have been using Synfig and Papagayo together to do lipsync and I have had success with one character, but I can’t figure out how to have two characters talking. On Papagayo, I have everything lined up and organized under two voices, but when I import to Synfig, only the first voice’s mouth is moving. If anyone has advice that would be great.
I am using Synfig version 1.3.3 with the OS X 10 operating system.
