The issue seems to be that there are commas in the column. I added a comma to the first row's name in the Big Class data table

and then saved it as a txt file using your export settings, and what I got was

What I suggest is for you to separate each comma field into separate columns

Set your export preferences to
![txnelson_3-1687616719850.png txnelson_3-1687616719850.png](https://community.jmp.com/t5/image/serverpage/image-id/54152i50BCBF760BEEDAC0/image-size/medium?v=v2&px=400)
and you will get
