I am using the premium version of this plugin.
At the same time I am using wpml.
For those who issue invoices on my site, only English is required,
but people checking the packing slip should be able to check it in one another language. (e.g. Korean)
The problem is that there is no way to set the invoice and packing slip to different languages.
I would be grateful if you could tell me how to solve this.
