Thank you for posting to our forum!
Looking at your account, I see AE listed twice on that particular order. I would recommend clicking Retry to send the order back to the Ready to Ship page. From there, you can click Edit for the Ship To address and format it like this:
You can see our corresponding Knowledge Base article here: How to: Format Military mail addresses
You can also double check addresses here: https://tools.usps.com/go/zip-code-lookup.htm
I hope that helps!
