free text fields input messes csv export

hey,
running a contact form with contact-form-cfdb7 plugin and 2 checkbox fields with free-text, lets call them field hobby and field color.
contact-form-cfdb7 creates a new column for the free text of each field.
the problem is when a non-free text answer is given, then the next field’s answer is written in fields-free text column, messing up with the csv table.
it only works if there is one free text field and its the last one.
for better understanding, i made a screenshot of some examples:
