Hello Paul!

Thanks for the screenshot of the error you are seeing. I am seeing these shipments have been moved from Ready to Print and back to the Orders page.  This error is in reference to the "from" zip last 4 digits. I did double check that those were correct and resaved the option.  Would you mind trying to process those orders again?  If the error comes back, would you mind leaving those on the error page so we can look into this further?

Thanks!
