Referring to the review above, I would like to share a few things to clear your doubts. We've been working on improving the Ultimate Addons for Visual Composer and making it a stable product that works with the latest versions of WordPress and Visual Composer. In such cases, we release updates with improved and additional elements that work great in all environments.
However, there were a couple of elements that were deprecated long back because they were found to be incompatible with the future updates of WordPress and Visual Composer. Although these elements were removed from the panel, the code still remains, so as to make sure we don't disturb the design of users who've used them on their websites.
In addition to this, the image grid element that you've mentioned is not a part of the Ultimate Addons for Visual Composer. Please make sure you are referring to the right element.
Moreover, I would like to inform you we have a dedicated support team who makes sure you do not face such issues, and if at all you do, we help you resolve it soon. Could you please cross check the issue at your end and contact us through our support center, so that we can check where the real issue lies?
