Hi Kathy,
We do not offer any tools that can be used to cancel active eBay listings from the Auctiva side of things, so you will just need to cancel these listings through your eBay account. Once you cancel them through eBay, they should be removed from your Active Listings page and appear on your Closed Listings page.
If you cancel some of your listings through eBay and they are not removed from your Auctiva Active Listings page automatically, I recommend contacting our customer support team using the form on the following page of our site: http://www.auctiva.com/help/requesthelp.aspx
