WC order numbers not going through to PayPal

I just integrated the PayPal Express Checkout plugin on the recommendation of PayPal; prior to this we were using the standard PayPal gateway that’s shipped with WC.

When downloading a CSV of transactions from PayPal, we’ve just noticed that the order ID is missing from all orders made since we switched to the PayPal Express Checkout plugin. All previous orders made with the old gateway have the order ID, but none of the new ones do.

We are using custom order numbers, created via woocommerce_order_number hook (it basically prepends the order number with two letters and adds 1,000,000 to the order ID), so I wonder if this is an issue with this plugin? Regardless, order numbers (or ‘Item ID’ as per the PayPal column name) are not getting through.

It is worth noting that the original order ID is getting through as part of the associative ‘Custom Number ‘object; so {"order_id":179,"order_key":"wc_xxx_xxxxx"} is getting through, but order ID SN-1000179 is not.
