Komodo every time you open a file, a wavy line always appears below the text

I do not know that there are often used Komodo to do the development of Daniel. Two days ago with Komodo, want to see some unused features. Just changed the middle line ending option to UNIX, which is the second option shown in the figure, the result ..... As a result, a wavy line appears every time you open it. You must manually change the line ending option to remove the first option. What's going on here??? Image:
