Scrolling does not work with Excitor & Ultimate Addon for WP Bakery Page Builder

My website uses Excitor theme & Ultimate Addon. Both are used by Rudux Frame work. Not sure if any CSS setting is misfiring but the scroll does not work. If the ultimate addon plugin is deactivated the scroll works but the header & title page changes to default theme.
In the plugin page (dashboard), the Ultimate Addon show as ‘Activate License’. When I purchased the Excitor theme, the plugin was downloaded. However if I purchase the plugin license separately then not sure if the scroll will work.
Any thoughts on this topic.
