Hi eclecticoldsod,
This is because eBay just split the previous "Royal Delivery" service into two separate options, which have not been added to the Auctiva lister form yet. We will be adding these options some time in the near future.
In the mean time, to post these listings successfully through your Auctiva account, I suggest replacing the "Royal Delivery" shipping option with an alternative like "Standard Flat Rate Shipping Service" or "Other(see item description)".
