Hi @brick
Welcome to the community forum.
When you changed the column names, you essentially created a new question, e.g., let us say you had a column name such as “Jenis_kelamin,” and you changed it to “gender”. The data collected under Jenis kelamin will remain in the column marked Jenis kelamin, and it will not be transferred into the column gender. This is because this is treated as a new question. So as it is, you cannot change the column name midway and have data remapped to it.
