I exported the Forms data using Export the selected data into CSV button and noticed one of the column header was showing field type not field name.
I checked at many places, couldn’t figure out. Later I checked on Content Editor – Forms and found that item name was showing the field type!
I gave the appropriate Field Name in Forms and the CSV file looks good now.
Forms Field Name sets Item Name and Label sets the Title field in Content Editor.
Don’t forget to publish the Forms!
