Google Playbooks dosnt render hyphenation

Just veiwed my Calibre conversion from docx to epub and checked the results in readers: Calibre, Nook app, and google Playbooks on tablet and phone, using generic page settings for most devices. Mostly looks great on both apps, except playbooks does not render hyphenation. Is there a setting somewhere or a CSS that will help control this?

Calibre 3.40, PlayBooks 5.0.5.
