I am being contacted by clients letting me know they can't checkout. They are being told an item is sold out when there is 1 in my inventory. When I tried making the inventory two, to see if that would allow the checkout my customer was not able to reduce the number she wanted to purchase to one. This has happened several times. I don't know what to do, as it doesn't seem to be happening on every listing, but unless someone contacts me I don't know about the trouble.
