Read More Link

I am trying to display the latest posts from a remote site using the post grid. The problem I am having is that the Read More button does not link to the original post but to the same excerpt on a page that it creates on the site.

It also inserts a phrase at the end of the post: The post Top Batting Types Needed for a Baby Quilt appeared first on Quilting With The Baby Quilt Lady. I don’t know where it is coming from or how to delete it.

I am also not seeing the featured images in the correct size. Regardless of which size I choose, the grid images are blurry.

Are these issues solvable?

Thanks
