Posting date duplicates with edit

Another problem with this same issue is that there is no way for people to leave a comment at the end of each post, even though I’ve enabled comments, pingbacks, etc.
BUT when I click on the date that I’ve described above (the double date), it brings up a comment form. Why is this happening and how can I fix it?? I’m sure no one would know to click on the dates to post a comment!
