The pingback you see on your site is a notification that another site has linked to your post. There is no need to reply to them. Instead, check on the site and make sure that they are valid and not spammy. If you look at the two pingbacks on the page you referred me to, the two sites are no longer available. I suggest you delete these pingbacks instead.
Hope that helps. Have a good day!
