Thanks for getting back here, Howard1144. Allow me to route you to the right support team to help you get this resolved.

Beforehand, to ensure we've got the right solution for you, it would be much appreciated if you could provide us with a screenshot that would help us determine what's happening on your end.

On the other, I'd recommend contacting our Customer Care Team again to help you assist further with the calculated average cost not updating. They have the ability to check and pull up your account using the screen sharing tool. Also, they'll provide workarounds once this issue is identified.

Moreover, you can check out this article if you wish to have adjustments in your stocks: Adjust your inventory quantity or value in QuickBooks Desktop. Also, this will help you keep your inventory status more accurate.
