Fix Shopify Blog - Article Is Currently Not Displaying

Currently, the blog on our website is not working correctly. I'm not sure if there is an error on the [login to view URL] file or the [login to view URL] file; however, the blogs which are published are not properly being displayed on the blog page nor on the front page slider. I have provided the Shopify template that has been installed for development purposes as well as link to the blogs that are not displaying on the current blog page and front page of [login to view URL]
