Import CSV Line Items Error workflow question

I have a question about the Import CSV Line Items workflow from Tiller Money Labs.

I downloaded a CSV and tried to import with the add on but its telling me that importer does not recognize the uploaded file. I tried two different files from two different institution and getting the same error.

The Import CSV Line Items workflow from Tiller Money Labs only works with the CSV formats shown in the sidebar, @Focal.Flash.Media.

There is a Basic Bank CSV rule that you can use if you first manually map the fields to a known format.
