Solved Modal popup box squashed

[mclernons]

Site is still under development www.officeasy.com.au
Joomla 3.6.5
Virtuemart 3.0.19.3 was 3.0.18 previously
ModernAStore template being used
PHP 5.6.30

When adding an item to cart modal box appears and sometimes the "Show Cart" and "Continue Shopping" will be overlapped.

What I've done.  Updated joomla from 3.6.4 to 3.6.5.  Updated VirtueMart to the latest. 
Not sure if this is a template issue, virtuemart or a joomla one.


Edit.  Found it was a font issue after it was displaying fine in Firefox and not in other browsers and all fonts looking the same except firefox.
