Portfolio grid images appear on top of each other

Hi,

Thanks for the theme firstly.

I am having a problem with my Portfolio grid not showing correctly. When the page loads you can briefly see the outline of where each box should be and then once the page is fully loaded it looks like they are all on top of each other meaning you can only see one at a time.

The page I am talking about is http://www.dogtech.com.au/dogtech-trainers

Things I have already tried –

– I upgraded with the latest version of Enfold last week. It seemed to fix the problem until I added more portfolio items

– deactivated all my plugins

– tried all the settings for display size, both manual and automatic

Thanks
