This problem accured in 2 of our collections. The latest is named Tomato 1.2 (copy), and I attached the CSV file here for you to see. It was first made in excel and than saved as a CSV. I built it by your visual example, though I didn’t quite understand the explenation about comma separation. One more question: I tried unsuccesfully to delete one of my collections (Tomato 1.2). Can I do it?
