Csv2transactions creating extra data

Just getting Tiller setup. Credit cards auto import with no problem.
Trying to manually pull in non supported checking accounts. I followed video
and other instructions but I get extra data pulled in that I don’t what it is or where it came from.
Shows under data added below.

Sounds like you’ve made it most the way through getting the script up and running, @zarcus. I agree the extra columns are wonky— and I’ve never seen the tool do that before— but since it is a one-time import, can’t you just delete those columns?
