Blog - Featured Image

Hello support,

I am trying to use Customizer - Blog - Featured Image.
But it doesn't work.

I entered my website a post with a featured image.
I don't want to show the image in the post.
I want to show the image only in the blog list.

So I enter the post and then Customizer - Blog - Featured Image.
I see the featured image.
I choose Featured Image = Hide.
I still see the featured image.
I choose Location = Below the Title
The image is still above the title.

What is wrong?
Can you help?

I also use GP Child Theme that I downloaded from generatepress.com website.
