Please send us access to FTP and wp dashboard on FTP with explanation and we`ll check it because it is really something magic. We have never seen anything similar.
Ok we get access and we checked your website. The problem is definitely related with one of your extra plugins. So the only way to remove it in your case will be below css:
.posts_group > h4, .posts_group > p { display: none; }
Comments
please send us url to your website and we`ll have a look on it.
.posts_group > h4, .posts_group > p { display: none; }
