If the label creation fails, you'll see a more defined error message that can help you pinpoint the issue.

Errors vs Warnings
When you're unable to proceed, that means you have an error rather than a warning. An error blocks you from creating a shipping label and requires you to make some kind of change before you can successfully create a label.
