Featured Content is changing as per column

Hi, I enabled Featured Content, it is showing 3 columns by default. I changed number of columns to 4, but its still showing 3 columns only. I checked using developer tool, and found that the class is showing as [class="featured-content-wrapper layout-three"], when i changed it to [class="featured-content-wrapper layout-four"], it shows four columns. so looks like when i change setting in admin backend, the changes are not reflected in front end. Can you please suggest? here is my site URL, and content is showing as "चारों दादा गुरुदेव", i want all four images to be in 4 column, and not in 3 column. Thanks
