Hi Tima,
I am really sorry for the delay of this reply. It seems like you have an override theme file for your notification page inside your current template and that is causing the issue for some reason. The file is located inside your /templates/ja_social_ii/html/com_easysocial/notifications/default.item.php. I've temporarily renamed the folder "notifications" to "notification_bak" and it is showing correctly now,

Hope these help.
