Hello！I noticed an issue: when a Customer is set to a certain language, any newly created Contacts will have the same language. However, if the Customer’s language is later changed, the existing Contacts’ language does not update accordingly. For reference, the first image shows Contact A (created before the Customer’s language change), and the second image shows Contact B (created after the language was updated).I also confirmed that the behavior remains the same even when logging in from a new computer.

Does the same thing happen in the NetSuite UI?

I didn’t see a language field on the Contact record in the NetSuite UI.
