Captivate 9 Bullet Style issues

In Captivate if you create a simple Text Caption with Arial font selected, Then try to apply Diamond style bullet List. The text box displays a rectangle shape instead of the selected bullet style. This happens with the Diamond and with all the style in the bottom row of style selections.
Eg. like the picture bellow:

Also some times instead of rectangle there appears 'w's instead of diamond bullet. This then gets displayed when publishing in HTML 5 output. This is really a pain.
Has anyone had this issue? I can not find anything on Google.
I have tried re-installing Captivate v9.0.1 several time but no luck.
Running on MAC OS X Yosemite.
Any one with a suggestion would be really appreciated.
Thanks
