Ok IOr1, but before you knock it out altogether, I would suggest that you file a support request with Auctiva directly.
Auctiva support should be able to sort this out for you as they can directly examine your listings and account settings.
The SG is a very useful feature, so clearly explain to them what is happening and what you have set and all should be resolved, but give them a few days as I reckon they are pretty busy at the moment finishing off the eCommerce store.
