Hey Nebojsa,
To clarify, this is not a theme issue. What you’re experiencing will happen to all builders that generate shortcodes in the WordPress Content or simply shortcodes inserted in the WordPress Content. That can happen to any theme and any plugins that put shortcodes in the content like Slider Revolution.
Some other themes might get around this by getting the title or some other content as the Open Graph Meta Description. We don’t do that in our theme because we believe that you must configure your Meta Description manually to utilize the Meta Description area best. If you’re not familiar with OG Meta Description area, that is this part:
My colleague said that you should use a plugin with Open Graph features which usually is included in SEO plugins. Please install one and set up a Meta Description for each of your pages. Also, deactivate the X Open Graph in Theme Options > Social to avoid conflict with 3rd party Open Graph features.
Hope that helps.
