Thanks so much for getting back to me.
Sure I will try to explain the issue in more detail.
Here is a Screencast video to help:

So the first thing I’m doing is adding a product to the cart when checking out.
When I get to the checkout page you will see a form with user information and then below that a bunch of tabs with forms being repeated a couple of times. The forms below the user information form are the issue.
I’ve concluded that these forms are coming from Tools -> Post Types -> New Post Type
As you can see in the video the New Post Type options within admin somewhat match what is being echoed within the checkout page for some reason?
This all started happening when I upgraded WordPress to the latest version as well as the Advanced Custom Fields Extended Plugin. Post Type feature also belongs to the Custom Field Extended Plugin.
