Compatibility with Ultimatum Theme

Hello! I’ve installed the plugin, however the ability to view the icons, change the links and add icons doesn’t seem to work in the Ultimatum theme. When I save the widget into my footer theme, I can view the default icons on the website, but I’m unable to view and change the social media links/icons in the backend.

Is there a solution? Or is the plugin just incompatible with the Ultimatum theme?
