HI Kmarie,
To display the full blog there you need to select the template name blog full content.
Create a page and at the right side there is template and select blog full content. Then your blog full content will display.

Also provide the site url too. Did you customize our code or some plugin may effect too. So deactivate all the plugins and check it once. You can also see in our demo site about it. Its working fine so it must also work there too.
