Hi
its little hard to understand the issue without having a look on the URL, because the position was already present.
you can add a new position above the heighlight position via layout file
Open template folder /layouts/default.php
Add this code after line 133
<div id="gkToolbar">
<?php if($this->API->modules('highlights1')) : ?>
<div id="gkHighlights">
<jdoc:include type="modules" name="highlights1" style="<?php echo $this->module_styles['highlights']; ?>" />
</div>
<?php endif; ?>
</div>
Here : http://prntscr.com/n7tmk9
Now open /templateDetails.xml" to define the new module position
<position>highlights1</position>
Here : http://prntscr.com/n7tnqe
If still there is any problem, i need your site credentials to see why module is not showing on this position, You can submit the details via Edit fields option in first post : http://prntscr.com/n7todo
