I cant import CSV file with specific columns

I’m unable to import my CSV file into GanttProject.
Nothing happens in GanttProject when the CSV file is imported.
Thank you for your support.
Import_Avanzit_Gantt_v1.csv (574 Octets)

The column names in the first row must be what GanttProject expects, rather than just arbitrary strings. You can look at the expected column names by exporting a project to CSV from GanttProject.
