Paypal Express blank shipping address

Hi, I cant find the solution to this on the forum. Paypal Express settings seem ok, links through from my site to Paypal ok. When customer clicks continue on Paypal it brings them back to my site but with a blank shipping address but with USA as the country.

Can anyone tell me how to enable a shipping address to come back from Paypal please? Zen cart version 1.3.8a

Thanks

Sure: Upgrade to the latest ZC version.

Several improvements were made since your version to handle things specifically like what you describe, in addition to many VERY important security updates.
