For anyone with the same issue, customer service explained what was happening in the Flatiron template. The blog landing page doesn't show the comments or subscription boxes, despite displaying the complete blog posts. The reader must click on the title of the blog post for it to take him/her to the actual blog post page where the comments and subscription boxes will appear. It doesn't appear that the Flatiron template allows thumbnail links for blog posts, but only displays the complete post on the list landing page, so it isn't intuitive to click on each blog post title since the posts are all displayed in full length. If there is a way to display thumbnails of each post in Flatiron blog, it isn't listed in the tutorials so I'm assuming that is not an option. I'll update anything I find out, but it seems the Flatiron template is limited in it's blog capabilities that way.
