I've been using the program about 6 weeks now and had lots of auctions, but my inventory items all still say "Never Listed". Not a biggie, but is there reason for this?

This is always the case when you use the Inventory to list your stock items. If you only use it to hold non-stock items, then they are ties one-for-one to an auction lot and the field shows the status of the auction lot. With stock items, multiple auction lots may be tied to the single item, in which case, no single auction lot's status could be shown.
