Allowing the shipping label to be printed more than once can result in duplicate orders being sent out.
We suggest that a message comes up asking 'if you're sure' you would like to re-print the shipping label.
This could be configurable in settings for people that don't want the feature.
Process the order after its shipped and this can't happen
Hi, we are aware of this feature and it is something we want to work on, however we have not yet planned when to do this, but likely to be in Q4 this year.
