"Theme options > Advanced > Theme features" in Avada not working


In Avada, version 4.0.2 I can’t make any changes in “Theme options > Advanced > Theme features”. Everything else in theme options works fine, just this. I need to disable open graph, however when I click on it nothing happens - I always see just that it’s ON.

Is there anybody, who can help me?

Thank you for any answer
