Quantity discrepancy in SS vs. Paypal

Site URL: https://www.coldmolds.com

First day with commerce site operational.  First order, customer ordered 6 of something but Paypal invoice shows a quantity of 1 (both totals are the same).  Anyone know a way for the PayPal invoices to reflect the correct quantity?

See screenshot - the order was for 6 molds (6x$25 = $150.00), and the flat rate shipping is $13. So it's right on the ColdMolds website, but the order is getting sent to PayPal as a single charge of $163.00

TIA!
