That's because you have that empty <li style="display:none"></li>. Is
it really necessary?
just decrement the index to start at 0:
$('#Themes li').each(function(index){
index--;
$('input:hidden', this).each(function(){
var fixName = $(this).attr('name').replace(/\[\d\]/, '['+index
+']');
$(this).attr('name', fixName);
});
});
