By default in that template in single Article view you cannot see modules published in Right nor Left module position. But it can be easily restore via custom CSS code:

@media screen and (min-width: 768px) {
.view-article #sp-main-body .col-md-9 { width: 75%; }
.item.item-page .entry-header {padding: 70px 90px 55px;}
.blog-details-content .blog-content-wrap {padding: 25px 90px 55px;}
}
.view-article #sp-left, .view-article #sp-right {display: block;}

Remember! To use custom CSS you should use one of above method:

• In NewsKit template settings > Custom CSS field
  OR
• Inside custom.css file which must be created inside /css/ folder of template
