The theme comes bundled with the Revolution Slider plugin under extended license. So, when you see a notification for “Plugin Activation” under Slider Revolution, this is meant for those who want to purchase their own separate license for their specific domain, and not for the slider that came bundled with the theme.
Instead, what you need to ensure, is that, under Plugin Updates, it shows that your “Plugin is up to date”.
We release the latest plugin updates with the theme - however, if you want to access the latest version of plugin before the theme is updated, you can always ask us directly and we will be happy to send you updated version of this plugin.
Thank you
