Hello Patrica,
What I think may have happened is that the BC default editor may have stripped a critical piece of data from the UL that is required for the orbit slider. The only way to fix it would be to upload the fixed template file and upload via Dreamweaver, or you can open the "Develop" tab and open the "Home Page.html" file in the template folder. The slider code should look like the code below paying attention to the "data-orbit" on the UL:
<div class="slideshow-wrapper touch" id="hero">
<div class="preloader"></div>
<ul data-orbit>
{module_webapps,....,a} <---- (your module number)
</ul>
</div>
Hope this works for you. - Curtiss
