Keeping the thumbnail created in Options causes it to be used on the blog page with the title--in large block lettering--as an overlay. I want this Thumbnail to go away from the blog page, but kept only for its connecting landing page.

I have the same issue and removing the thumbnail on the post eliminates the ability for this thumbnail to be used on my blog landing page. It simply pulls from the post's image, which is not scaled for a thumbnail (square) space. Of course, I could adjust the aspect ratio in the Edit >Design box of the landing page, but then that naturally affects all other images. Ultimately, I want the blog page to have a 4:3 image below the title and landing page to have a 1:1 thumbnail image.
