Ajax next button not working

Hi,

Great theme. We have an Ajax portfolio several places on our site but the next and previous button seems to be tripping up. The content from the previous still shows and then eventually just completely stops working. The page that is having the most issues is here: http://alphaplantbased.com/products/ so you can see yourself. We inserted short codes into the preview area… not sure if this is what is causing the issue. Can you please take a look and let us know if there is a fix. We have a presentation to some investors tomorrow and would like to have this issue resolved.

Thanks!!
