Address missing when store owner tries to print labels from PayPal

[TecBrat]

This is a Zen-Cart running version 1.3.8a.

We are using the shipping module "PayPal IPN - Website Payments Standard"

The Address is missing when store owner tries to print labels from PayPal. When logged in to the paypal account, viewing funds received, there is a "Details" link and a "Print Shipping Label" button that should both show the address. Neither do.

I have turned on logging but don't have any full transactions yet. Here's a snip from one of the logs for a transaction that I didn't complete though:

Some information obscured. Where you see all the "X"s, there was real data.

Any ideas why this isn't working?
