Before this change, you were sending the items subtotal prices instead of the product price. So in GA it was causing a problem. For instance if I have a product with a price of $5, if I buy 2 of them, it will send $10 to GA instead of $5. And GA will do 2 * 10 = $20 as the product price.

Also the order discount and coupons were missing.
