Hi @nblund,
I have seen that the mentioned layout is under the Single. I am not sure whether it has been created with WooCommerce Archive or just the Single type of layout in the previous version, or it is showing under the single in the updated version even though has been created as WooCommerce Archive. I have created a WooCommerce Archive and tested it by assigning it to the Shop and it worked perfectly fine. If that does not help, please elaborate on the matter a bit to understand the problem.
Thanks
