Rightside bar single listing page widget

Please asking for help to solve this problem

After adding any widget to the rightside bar on the single listing page, it does not display as expected, on the side bar. Instead, widgets are displayed below the main listing details while the sidebar appears to have been created but is just empty space. If widget is removed, the single listing detail goes back to ‘full width’ with side bar empty space gone.

Note, im just starting out testing this great plugin on my new site using the Directoria theme.

Thanks.
