Problem:

The issue here is that some of the user's posts were displaying differently from others.

Solution:

Upon checking the user's website it turns out that some of their posts didn't have their content template assigned to it.

If this is happening to you then I would recommend going to the Content template that you've made and under the Usage table click on "Apply to All". This will assign the content template to all the posts under the assigned post type.
