Why aren't product tags appearing in order history?

I’ve setup a tag for some of our products, but the tag is not showing up in the order history.

In the attached pic you can see that the tag is setup and it works when I filter the products. But it does not work at all (filters, listing) in the order history.

Bug or user error?

Thanks.

Logic or rather UI error on behalf of Shopify I’d say. Tags for products are not equal to tags for orders. In the order list view you have no connection to the product tag. What is it you want to find out? Which order is for a certain product?

Just wanted to filter by Tag.
Thinking about it, an order could include products with a variety of tags or none, so I can see why you label it a UI error. How do tags get assigned to an order?
Thanks for clarifying this issue.
