I've recently started running OSC, and have run into the following problem:

Customer places order. Selects Flat Rate Shipping (only option offered for International orders). When the order goes through, the invoice that shows up in the OSC Admin does not display the product name; it shows the price and quantity correctly.

The problem appears to be only when flat rate is selected. Domestic orders that go UPS are OK.

I'm at a loss to figure it out - Does anybody have an idea where to look?

Thanks in advance.
