Uh, let's say I have a hundred lines to delete on this character. I used Non-empty lines Filter, and it showed only a few lines. Are those the only lines I have to delete?

On another not:

* Non-empty lines filter provides lucid view of a DLG file and displays only lines that contain some actual text to be modified or translated.

That's the idea. "Non empty lines" shows only the lines that have actual text in both, the male and female entries. And that are the only ones you have to be concerned about. If the background is green, delete the female text. If it's red, don't.
