When export no tasks in description but show in bar's

When I export to pdf none of the descriptions are in the pdf yet the bars are there , so no name, dates etc
am I missing something and should switch it on. I currently have to open in old version and then export which is pain

I work on Mac

This issue was discussed a few times, see the links below

TL;DR: use GP 3.1 and choose “Droid Sans Fallback Full H” application font in the settings.
