I am not quite sure what you are trying to say here. Seems to me the text clearly has more than one line.
If you're saying that it shouldn't, because you have already split it, then that is because you are looking at the wrong variable. You have your %CurrentItem%, which is a data row with the original data you extracted from the web page. If you used Split text on %CurrentItem['value #3']%, you should have stored the outputs of it in a separate variable, that should be a list of text rows.
If the text in this column is not expected to have new lines, then check your extraction parameters. But I can clearly see there is not even 2, but 3 lines in there, with the second one being blank. It's like you're extracting two paragraphs.
