Hello PhilthyCollins,
The eBay relist profile and the Auctiva auto-relist profiles do not communicate with one another, so we recommend that you use one or the other to avoid any duplicate listing events.
I hope this helps. If you have any additional auto0-relist questions, please contact our Customer Support team directly from under the "Help" tab within your account and we will do our best to assist you.
-Michael
