@BanhMiBoSua Thanks for the information, hard to say if this issue is a model limitation of the locale or there is a bug without seeing the invoice sample.
Let's raise a support ticket so that support engineer can help you under a privacy protection process, as we suspect this issue is caused by wrong locale setting.
Please let me know if you have no support plan, I am happy to enable you a free ticket.
Regards,
Yutong
