Missing the panel "1/4" in PDF export.

Hi! I must be blind, but I’ve been exporting my files to PDF and on some files, each panel shows the total amount of panels in the scene, but other files do not. For Example, the Panel box will say “1/4” in one PDF export of SB file, but in another file it will export as just “1” without a total panel count. I’ve probably just unchecked a box somewhere, but I don’t know how to fix it! Help please :)Also, I’m using Storyboard Pro 1.6-Matthew
