Comments in Responsive on directory listing not working

I am having the following problems with Directory Press responsive theme in the area of Listing comments.

Using Internet Explorer, when a customer is trying to leave a comment on a directory listing using the comments tab, the field labels do not appear so the user cannot see what data gets entered into each field to leave the comment.

So, i thought perhaps I’d find a better comments plugin to see if that helped. Installed DISQUS. But now I cannot submit a comment at all either. Appears the theme does not work with any comments plugins when trying to submit a comment on the directory listing.

Anyone else having this issue and can provide any insights?
