Why is the location field empty in my order export?

Hi Guys,

Our store has three fulfilment locations, which work as intended in the Shopify app. Upon exporting orders however, the location column is blank:

We need to see the line item location in our reporting and for integration with our accounting platform, though we have not been able to find a way to export this information. Was there a workaround for this or is something not checked etc?

Any help appreciated.
