Yeah, I found this myself by going to Joomla.org.
Open the templateDetails.xml file.
Search for Positions (it looks like this):
<positions>
<position>hornav</position>
<position>breadcrumbs</position>
<position>banner</position>
<position>left</position>
<position>right</position>
<position>ja-hpanel</position>
<position>ja-slideshow</position>
<position>ja-tabs</position>
<position>ja-login</position>
<position>top1</position>
<position>top2</position>
<position>topsl</position>
Add:
<position>ja-slideshow</position>
And Save!
Still wish is was corrected in the template.
