Form field initial value and form translations

Form field initial value and form translations

I have a hidden form field 'Language' that holds the language of the form.  Starting from creating the English version, I have set the Placeholder text, and initial value both to 'English'.
When translating the form I get an option for translating the field, so I have entered French as example.
When submitting the form I still receive 'English' as the value. It seems that I am only translating the placeholder text and not the value?
Could someone help me to solve this issue?
