Hi Barb,
This sometimes happens with imported listings and we are currently investigating why. To correct this problem for the aforementioned listings, I created a new version of each, that you should be able to find at the top of your saved listings page, by copying all of the auction information into the "New Listing" form. You should now be edit or post either of these listings using the new copies that are not labeled as "Imported Listings".
If you run into any further difficulties, please don't hesitate to let us know!
