inventory quantity management: sell/inventory conflict with seller hub
I used the api to create an inventory item, create an offer and then publish it. I put an inventory quantity of 5 in the inventory api and that shows in seller hub. The live listing shows 5 and all appears okay. Then I get more inventory (7) to sell and update the listing in the seller hub GUI. Now is where it doesn't act as I expected. The listing still shows 5 available. In the checkout process, I can select 7 in the pull down menu to purchase, but then I get an error stating "the seller does not have that many left." How do I modify the inventory/offer or listing to be managed by the seller hub GUI?
