Having trouble unfollowing specific accounts.

I followed a bunch of those reddit story channels while scrolling on my FYP I like them but now when I go into my following feed its all that shows on my following page. So I started going through my following page and unfollowing the reddit story tik tok pages but there are some that pop up in the pics im going to add. 1st Pic is the reddit story page the little gear icon like the 2nd Pic is not there. Any idea how to unfollow this account without having to scroll endlessly through all the accounts I follow?
