trouble with wp_list_pages

I am trying to edit the “page.php” file in my theme with the following code to display only the child pages of the current page-

<?php
			$children = wp_list_pages('title_li=Pages&child_of='.$post->ID.'&echo=0');
			if ($children) { ?>
			<ul>
			<?php echo $children; ?>
			</ul>
			<?php } ?>

This is taken straight off of this codex page- https://codex.www.ads-software.com/wp_list_pages

What happens though is I get two sets of unordered lists like in the below code. I want it to appear like the first set where it is only the child-pages of the current parent, but as you can see, the first url does not obey the ‘title_li=Pages’ that I put into the wp_list_pages(), the second ul does. But the second ul displays the parent, siblings and child pages. What the heck is going on?

I can get rid of the if() and then it only displays the first unordered list but that still doesn’t fix the problem of it not obeying my title_li .. HELP!?!
