@zewditu This is a tab separated file right? And you changed it to a comma/semi-colon? If yes, this looks expected to me. You've changed the separator to a comma/semi-colon. There are no comma/semi-colons. When it tries to parse the file it thinks it is one column because there are no separators found. When printing, it puts the tabs into the printed lines. This makes it look really weird, but it's doing what you told it to do.

@beccamc yes, it is expected, thanks for your explanations.
