Featured Image is not getting disabled for single post

Hi, I am currently facing an issue with the featured image. I use an Astra theme and classic wordpress editor. The theme displays the featured image on top of the title which I don’t want hence I used to disable it for all single posts using the “Disable Featured Image” option but now after the update maybe, it overrides my request and still displays the featured image. Now two images are displayed, one before and one after the title. I do need to add featured image so it displays on the thumbnail. Please let me know how do I disable featured image on single post view for all posts.
