CS CART 3 - USPS International Priority is defaulting to FIRST CLASS

Anyone else have an issue with this?

I selected Priority INternational but it is acting like I selected First Class because FC is limited to 13 oz.



Shipping service: USPS Priority Mail International Weight: 2 lbs Error: First Class mail must weigh 13 ounces or less. / Service not available.

I've been getting the same error - if you hear anything, let me know - all my International customers are paying huge amounts for Priority International and I'm having to refund.
