Switching from Product Options to Inventory and back erases Achive options

I can’t say when this started, I think with the latest big WooCommerce update. I’ve tested it on 3 separate production websites. When I’m in Product Options (WooCommerce>Settings>Products) and have some Product Archive options selected, I move to the Inventory link. It doesn’t matter if I make changes or not in Inventory, but when I go back to Product Options, all of the Archive settings get erased. Can you help?
