MarketPress: PayPal Chained Payment not returning order info shipping+tax+coupon

Hello,

When buying a product with PayPal chained payment, the following information is not returned in the "order confirmation email", "tracking order page" and "order details page for merchants"
- shipping
- tax
-coupon
Only total amount of the order is returned.

It works fine with PayPal express checkout, but not with chained payments.
Please see the screenshots below with chained payment purchased vs express checkout purchased.
Is this a bug? Please help me with this issue.

Thank you
