CSV import - cannot deselect/clear a field once it has been selected for a row

What is the challenge?

When doing a CSV import. you select the Aha! field each column corresponds to. Once a field is selected for a column, you cannot clear the field so it is no longer mapped to an Aha! field.

What is the impact?

Currently I have to start from scratch to be able to leave a field open/unmapped, e.g. when I accidentally mapped it then realized that I don’t have the proper .csv column data for that field.

Describe your idea

Be able to clear a field mapping for a column in the CSV import after it is selected.
