Conflict with plugin

Up until the most recent update to Wordpress 4.6.1 everything on my website was working fine. Now after deactivating all plugins and reactivating them one by one to diagnose the problem. I found that Custom Sidebars causes my other plugin Tabby Responsive Tabs to not function properly. If you would go to my website " " you will see that if you click compare on any of the blue buttons the bottom info changes as it is supposed to but reverts to its initial state after a second. Any ideas what could be causing this?
