Were these widgets in place before or after you activated the Beautiful Pro theme? As far as I’m aware, if a new theme has a different set of widget areas, you may need to reassign them, which would be why they’d be in the Inactive Widgets area.
Generally speaking you control your widgets from the page titled Widgets under the Appearance menu item in the dashboard. Some themes control widget-like areas on a page by page basic though, so you could look there.
