Does not work in lists for editors

For the role Editor, in the list of posts, pages (and other contents activated for ns-featured-post), the column “featured”…

• Shows two bullets : one checked, one empty.
• By clicking on its, nothing happens.

Why? Because admin.css and admin.js are not loaded in the admin page.

The issue is solved when, in class-ns-featured-posts-admin.php, I remove this lines :

if ( ! current_user_can( 'unfiltered_html' ) ) {
   return;
}
