JigoShop API subtotal is incorrect? [Potential Bug]

I’ve been getting to grips with the API and as far as I can tell
$order[‘data’][‘subtotal’] and $order[‘data’][‘total’] are usually the same.

The subtotal always includes shipping.

If there’s a discount active then the subtotal is pre-discount but still includes shipping.

Example:

Subtotal
￡31.45
Discount
￡9.39
Total
￡22.06

(+￡5.99 shipping)

Shouldn’t the total be the final total, including shipping?

It’s easy to code around, of course, but a total should be the final amount. Similarly a subtotal shouldn’t include shipping.
