One thing to check is if you have the line endings set correctly. So you could try changing that setting and see if that helps. Another possibility is that there is a stray “quote” character in the file, which would cause all subsequent semicolons to be treated as part of the text, and not as delimiters. You will want to confirm that both the quote character and escape character are set correctly.
Just in case your issue is not resolved yet. It could be related to the endline delimiter. See if changing it from “\r\n” to “\n” or vice versa will help
