When you see a document ID in italics in the console, that document doesn't actually exist. It's shown because that document ID has subcollections nested under it (which you are not showing in your screenshot. If you want to delete those subcollections, you will need to query for and delete each document in those subcollections. There is no easy way around this in client applications. For server-side code, there are tools to delete a document and subcollections recursively.
