Featured Images appears in post

Hi Sir, Thank you for this great theme. In my every post same Image is appearing twice. Is there any way to remove the topmost image [featured image] which appears on post. I do not want to remove the uploaded image. Also I checked if I uncheck the featured image in post it also disappears on Home/Category pages. So I have to stick with feature image facility in WordPress. But it creates a problem with post pages. You can check the Url – https://www.lifelords.com
