Business Directory Plugin With Enfold Issues

I’m using Business Directory plugin with Enfold 4.1.2. On mouse over of the thumbs they carriage return down the page into a column. The light box effect still works and the images can be viewed in larger formats but this problem does not happen when I switch to another theme. I have disabled light box in the Enfold Apanel and after speaking with the plugin owner, they say it would have to be an issue with the theme. Any ideas?
