Importing tasks in CSV file not showing

Hi there, I am new to Ghanttproject and have set up one project manually and now trying to import tasks from a spreadsheet of tasks. I have set up the import table with 6 column headers and have a series of tasks. saved as a csv file and tried to import. I have got mixed messages searching for a resolution on date formats and any other issues that may be a problem. Basically when I import nothing happens and the new project has nothing it it. Can someone help advise so I can save a lot of work using an import feature. thanks

Please share the CSV file.
