Hi byrk,
Thanks so much for your report, and welcome to the forum!
If I understand the report correctly, you’re managing the stock for your variable product on the product level and the variation level? So the item stock is set to “0” or “out of stock” at the product level, but xx variations are available?
From my point of view, it would be either one or the other. For variable products, I would use the variation level. But maybe I have misunderstood stock management so far.
