I have a customer site we have been running for a few years which uses WooCommerce and the payment gateway is Paypal. It has been working just fine for a long time, but lately there i a strange problem. We use a flat rate shipping method btw. Everything is $5.00 basically. Here is the problem When a customer orders multiple amounts of the same product, the shipping looks fine in WooCommerce. As soon as it goes into Paypal shipping is showing up as $10 (it doubles this flat rate amount). If the customer order different items at the same time, then it works correctly. Any idea what could be going on?
