In bulk “Remove Featured Image” from all posts

My problem is that I need “Featured Images” for the picture to show up in “category”, “search”, and on the Index page.
but if I use Featured Image than it appears twice in the same post from the post view.

Is there anyway quick way to remove the featured image from every post on my site?

I know how to do it by editing each post, but I am hoping for something a little quicker than that.

I also don’t know if this is a theme problem (I use Themify Magazine paid version) or a WordPress problem.

I am not smart enough to know the difference between the two.

Thanks for considering this question
