Welcome to the Q&A Forum

No problem. Screaming Frog (or any crawler) won't pick it up, because it's not being linked to within the website (it's an "orphaned" page). Google could still index them because they are in the sitemap, but it took so long because they are no actually linked to from the website. So... if it's not supposed to be indexed at all in the first place, you can add a meta "noindex" tag to the page and remove it from the sitemap. Then you'll be all set
