I did exactly what you said. I uploaded all the original files even though I hadn't modified them. I reset the status of three ads to "0". All three of these ads showed multiple items available.
I did all that last night. This morning, all three ads were marked sold. The status on all three was changed from a "0" to a number, quantity had not decreased. Seller emailed me to let me know that he had actually sold NONE of any of the items.
I truly don't understand this one.
