I'm having trouble with querying English pronunciation from commons by my bots. Take a look at queries below:<br><ul><li><a href="http://commons.wikimedia.org/w/api.php?action=query&list=categorymembers&cmtitle=Category:English%20pronunciation&cmlimit=20">title=</a><a href="http://commons.wikimedia.org/w/api.php?action=query&list=categorymembers&cmtitle=Category:English%20pronunciation&cmlimit=20">Category:English pronunciation</a></li>
<li><a href="http://commons.wikimedia.org/w/api.php?action=query&list=categorymembers&cmtitle=Category:English%20pronunciation&cmlimit=20&cmcontinue=used%20to%7C">title=Category:English pronunciation&cmcontinue=used to.ogg|</a></li>
</ul>There are 4 items appear twice in these 2 queries: <span>wherewithal, </span><span>wires, wire, wired and items are sorted in no order.<br>What's up?<br></span>
