Comments Heading Issue

Hello!

I have been enjoying exploring this theme and love it so far. I have come across one issue and I can’t seem to find a place to change this in the theme options, so I am hoping someone can point me in the right direction.

When there is a comment on a blog post, for some reason a header is displayed above the comment that reads “One Response One Response”. I am guessing the heading is not supposed to repeat.

Here is an example of what I am experiencing: https://www.kellyjoraines.com/michele/fair-not-really/

I would appreciate any insight!

Thank you!
