"Full width" template for projects don't seem to work in Child theme

Hi,
I show my projects in full width with no sidebar using the Shapely theme and it works perfectly. I want to make some changes so I’ve created a child theme. For now it’s a dummy (the style.css and function.php files only have the minimal content - template name and enqueue function).
When I activate it and copy ALL THE SETTINGS from the shapely theme, including the custom css, the projects show with an (empty) right sidebar whatever template I chose for them.

Hi there
