Level 2 Model Building: Sprint 1, 18.104.22.168 Nothing is imported to the flat list
Following the "22.214.171.124 Import Data into Country Flat List" of the Level 2 Sprint 1 modeling building. I cannot import CSV files to the county's flat list. Please refer to the screenshot for steps and details.
Since the list is very small I can easily do it by adding manually, however, since this is a tutorial I would like to know why it's "failed".
