<p>There's a small display issue when there's only a single child bundle available for creation on the Reorder children page. Since the action buttons use a dropbutton, the display breaks when there's only a single bundle:</p>

<p>Multi bundle:<br>

<p>There's also a small issue where the Update child order button still displays when there are no children.</p>
<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>Render a normal button when there's only 1 child bundle.</p>
