I have only a vague idea about language support. My guess is that you will want to create the form in english first, make sure it is ok, export to XLS format, translate it, and import as a new form. However, some of the instructions that are built-in will still be in English. (Getting over my head here.)
To see your values, try downloading in XLS LEGACY format. This shows the unique Id column. I am not aware of any download that has both the label values and the ID values, which seems very odd to me. Hopefully, I am missing something.
