Theme Horse

I’ve been trying to setup the blog like in the demo

https://www.themehorse.com/preview/ambition/blog/

However, I can’t get the right sidebar to be on the right.

I set the page as the posts page through Settings->Reading->Posts Page

And selected the “Right sidebar” under Below setting will not reflect on Business Template, but it still doesn’t work.

Here is the picture:
