[O] Exporting to LaTeX Ignores Title Option in #+Options:.

[lists]

I have a bunch of org-files that I want to export. They  all have a 
#+TITLE: but I don't want the Title to appear in the exported code.

If I export the following minimal file:

#+TITLE: My Title.
#+AUTHOR: Ian Barton.
#+STARTUP: content indent
#+DATE: [2016-06-18 Sat 07:43]
#+OPTIONS:  title:nil

I get the following output:

\author{Ian Barton.}
\date{\textit{[2016-06-18 Sat 07:43]}}
\title{My Title.}


I thought that setting title:nil in #+Options: suppressed export of the 
title. Is this expected behaviour with LaTeX?

Ian.
