how to change the Primary language of a Microsoft Form (or export in an Additional language)

I have a multilingual form with a 'Primary language' of French and 'Additional language' English - if I export to Excel all questions and responses are downloaded French (I assume because it is the Primary language), no matter the language the respondants used, but I need the answers in English. Is there a way to change the Primary language in an existing Google Form, or is there a way to export the answers in an Additional language?
