The nova flavor-delete CLI will output the deleted flavor information rather than confirm that the flavor was successfully deleted, or simply not show anything on successful deletion, which is odd from a user experience perspective. CLIs to delete resources usually just don't print anything on success.
Compare nova flavor-delete behavior vs openstack CLI flavor delete:
