Usually it takes some time to update the "vendor" items to the proper information behind it. Everything should be scrapped and updated in the next from 30 minutes to 2 hours after the item is added (depends how loaded the system is). If the "Vendor" stays for longer than two hours, you can force recheck and reprice the item and everything should be fine ( if nothing changes , then you can open up a new ticket with 2-3 examples so we can investigate further)
