Jetpack Comments form not showing

WordPress Theme twenty Ten, WordPress 3.9, Jetpack 2.9.3. GinnyMoe.net is blog. I used to use Jetpack comments, and it worked, but I changed to the jetpack Contact Form and feedback. Now I want to try the comment form again. I activated it in the Jetpack plug-in page and configured it. people are allowed to post on new articles and they need not be registered. “Leave a comment” appears below posts, but nothing else. When I click “Leave a comment” it takes me to the single post instead of any kind of comment form. What should be happening and how can I get it to happen? Thanks in advance for any help. (By the way, I am no computer programmer, easy is best for me. If you have a better comment form I am open to it, trying to change to reduce spam.)
