When I go to remove stock via Advanced Stock Manager I just get a message like the following:
"You don't have enough usable quantity. Cannot remove 31 items out of 0. "
In this example as attached images will show, there is actually 2500 units in physical AND usable stock.
The warehouse setting is the same for the product and the warehouse management.
The follow may or may not have something to do with this issue. Due to another bug the site has/had the original products in the site before the site was turned into a Multistore would not show the Add to Cart button in the site once it was converted to a Multistore. This bug has been recognized. So I had to duplicate each product to get a fresh product version for them to work. The new/duplicate products now show the Add to Cart button and seem fine. I just added this in case something did not work with the duplicate product solution.
This is becoming a nightmare.
