The problem stays at different height among articles, so they can not be organized properly.
By defaul, the height of articles showed in that module is calculated by the js and are same among articles. However, there is js conflict in your site (http://prntscr.com/4pgspx), and this may cause the js can’t calculate when the content hasn’t been fully loaded for the first time.
What I can suggest you in this situation:
1. Try to disable plugin/module one by one to find the one cause the conflict.
2. You still can set the height, so your site will display fine even the first time: Add the below code to the root/templates/ja_fubix/css/custom.css
.trending.vertical-layout li{
min-height: 420px !important;
}
