Again the proviso: I'm winging it here.

I think you need to create Profiles for various listing scenarios. Profile 1 for auction-style listings (1, 3, 5, 7, or 10 days); Profile 2 for non-Store BINs; Profile 3 for 30-day or GTC Store items; and so on. If you are in a Store Profile, and you inadvertently enter a starting price as if it's an auction-style listing, I think AW asks you if you want that to be the Buy Price, and if you click Yes, the program moves that figure to the proper box.

The only thing I can come up with is that you don't have your Profile properly configured for your Store, and eBay is seeing the listing as an auction-style and is rejecting it because there are no 30-day auction-style formats available.
