I am using the Business Page template with all widgets. Some use the information from the corresponding page/post and appear translated correctly. The problem is with those widgets where the content is written on the widget itself:
1- Featured page: description text
2- Recent work: title and description
3- Promobox: primary and secondary promo texts
The section you are talking about are the fields where user have full control with their content.
You can simply edit the content and write it with the language that you want to.
