Im using Exstream communication builder/streamserve. Calibri font won't print out

After deploying my project at the control center, I'm expecting a PDF file containing all the design that created at the Story Teller. There was a PDF file but when opening it, the font seems doesn't there. I tried with arial, and it worked just fine. Back on the logs at the control center, it shows "(font, not found in): Calibri, PDF2. I can't find where is the PDF2".
