How to remove featured image from inside single post

Hello,

I’ve included a featured image on my sticky posts so I can feature them on my homepage.

However, I can not remove the featured image from appearing inside the individual post above the post title.

An example of the page this can be found here: https://felicitymacintosh.com/me/

Please may someone advise how I can remove the featured image from appear inside my posts.

Many thanks, ??
