As far as we have checked the issue locally with the latest version of the theme and WordPress in PHP 5.5+ , we are unable to find such issue.
Also it is likely that the issue might have been caused due to the use of PHP’s APC for caching.
If you’re using caching on your site, try switching from APC/memcached cache to disk caching and see if it clears up.
Also please mention your PHP version , WordPress version and Hosting server your site is currently hosted on so that we could look further into the issue .
