Starting in mid-September, Amplifier will began showing Alerted Orders. This new status type will allow you to see those orders that are currently unable to progress to shipping.
Issues that cause Alerts can include:
Bad Character Codes (e.g. Unsupported Foreign language characters)
Unsupported Ship Methods
And so on
Because this is being added as a Status type, you can filter your Order View to only show the Alerted ones.
Historically, Amplifier's Help team has manually corrected your Orders for you. In the near future, Amplifier will roll out new features to let your team directly fix some of the more common issues that prevent Order allocation.
