Vietnamese translations not applied in Expense Claims and other modules

Hi team,

I am facing an issue with the Vietnamese translation in ERPNext.

Although I have set the system language to Vietnamese and cleared the cache, some modules such as “Expense Claims”, “Advance Employee”, and other labels still appear in English.

I would like to ask:

  • Is this due to missing translations in the language pack?
  • Is there any way to force these items to be translated properly?
  • Should I contribute translations somewhere or is there another solution?

Attached is a screenshot showing untranslated labels.

Thanks a lot for your support!
