Removing deleted content/Cache purging

I've deployed my static jekyll site via the Amplify console, building successfully a few times now. My most recent commit deleted a bunch of posts and other files, but many of them are still accessible through the domain. I'm wondering if the deleted files weren't actually deleted from static storage, or if the CDN cache needs to be purged for those particular URLs, and how we would do either of those?

EDIT: To clarify, some of the stuff deleted in the commit is correctly no longer accessible, but some is. The only reason I can think of being that the still existing ones are cached for a long time.
