Not Displaying in Posts

I’ve successfully imported my campaigns from Mailchimp, but when I embed a campaign using the shortcode provided in the FAQ’s it only displays a hyperlinked title on my Posts page. Then there is a big empty space as long as the post would be were it displayed before the next, older, post. If I click the hyperlinked title, it does take me to the campaign, but I would like it to display on my actual posts page. Any help? Also, although the campaign ID’s appear to work, the archive URL leads me to a 404 Page Not Found message. I have already switched the permalinks to “Post Name” as suggested.
