Plugin: blog designer, Want posts to show in same page

Hello

When I click on my post from the blog page, it directs me to a separate page.
How do I make the post show on the same page when I click it?

Blog page https://www.9minday.com/blog/

Want the post to show in the same page like this demo. https://blogdesigner.solwininfotech.com/demo/blog-spektrum-blog-template/

Thanks
