Laravel - How to revert local storage symlink and refresh

Question

When I save images to storage they show in the storage/app directory, but they don't show in public/storage. I also noticed that a storage/app/public directory seems to have been created which also contains everything within storage/app.

I can't work out how I managed to cause this mess, and I think it might make sense to revert these directories to how it should have been to begin with (with a new laravel project), remove any existing symlinks, and start again - does this sound like the best approach? And how would I go about doing this if I have set the symlink up incorrectly?
