J-BusinessDirectory - J-Business Directory Storing reviews twice.

Hi,  I started having this issue after I updated joomla to latest version (3.3.6).

When a user writes a review for a business it is saved twice in the back-end. And it also shows twice on the front-end of the website.
If you go on the following link and at the bottom of the page under "Testimonials" click "Write testimonial" and then write and save a test review. After that you should be able see that the review shows up twice in the "Testimonials" section.

Thanks.
