Bug with getting store

[KeithViking]

Created a new Umbraco 13 CMS.
Installed commerce.
Watched video on Umbraco Commerce for setup.

My structure=

Home
-Items : Store is listed here
--Item
-checkout
-About
-Contact
-Gift Items

Using the code from the video when I get to a page requesting GetCurrentOrder(storeId) the store is null. This occurs on the Gift Items node. I felt the gift items page would go up to the Items page to get the store value.

I am using Fallback.ToAncestors with alias store.

If this layout is not sufficient for multiple stores, could you advise what kind of layout would work with multiple stores?

According to the documentation and video I can have multiple stores at different nodes which go up the tree to find the alias store, so I can't confirm if I've missed a step or if this is a bug?
