I think it's related to lazy loading. As this tutorial said:

Lazy loading is delaying the loading of related data until you specifically request for it

You never ever request related data directly in this code snippet, so the expectation of loading related data is wrong.

If you wanna load related data at the moment, you can use Include to achieve that:

db.StockUOMs.Include(i => i.UOM).Include(i => i.Stationery).ToList();

for a deep dive, you can follow this link.

good luck.
