@Nabeel is the one who created the post using the Motivational Hero Video page template. Your very first post was this: “
I am trying to create a post that has the template named Motivational Hero Video.” This is why @Nabeel created the post. You then mentioned that nothing is displayed in the Blog index and I was the one who pointed out that because there was no featured image. Now that you have added it, you then again have another issue that when you view the post, you are seeing the featured image and all those images and elements from the Motivational Hero Video template.
In my opinion, you must have misunderstood the Motivation Hero Video template vs the post/page template.
Page templates are a specific type of template file that can be applied to a specific page or groups of pages.
Post Template Files:
There are many template files that WordPress uses to display the Post post type. Any content dealing with a blog or its posts are within the Post post type.
The Motivational Hero Video and All Content Templates that you find in our Design Cloud are templates that you can use to create a page or a post using the Cornerstone or the Pro Editor which is our own page builder. Any of these content templates will need to be used accordingly with the help of the different page templates that we have built-in the theme. For more details about the different page templates in the theme, please check this out:
Regretfully, we do not have built-in Post Templates in the theme. Those content templates may be used to create a post, you may not achieve the best results compared to using the content templates in creating a page. This is also why @Tristup responded that you need to create your own custom Post Template.
Hope this explains it briefly.
