Sidebars showing default content (Pages, Categories, etc) instead of widgets

Some of my pages and posts are only showing the default sidebar content (a list of Pages, Categories and Archives)

I cannot see any reason for this and have tried searching the forum but can’t find a solution.

I’m running the latest version of Enfold and the latest version of WP.

The only thing that is perhaps worth noting is this site was built on another theme and then recently I switched the theme to Enfold.

Home page has widgets showing in the side bar correctly – http://www.moscowexpatlife.ru/

Inside page with correct sidebar – http://www.moscowexpatlife.ru/issue-17-winter-2016-2017-index/

Page that I cannot get the sidebar to display on – http://www.moscowexpatlife.ru/partners/
Another page that the sidebars won’t work on – http://www.moscowexpatlife.ru/networking/
Another page with teh sidebar broken – http://www.moscowexpatlife.ru/past-issues/

Posts Category page with the sidebar not working – http://www.moscowexpatlife.ru/category/moscow-good-food-club/

Thanks!
