Hi, you can delete the content of such lines with regex search and replace (Ctrl+H) for:
^.*<Untitled>; \d+.*$
replacing with
empty string
however, the blank line (the newline only) still remains in the text. If there are no meaningful blank lines in the text, these ones can be removed via Edit - lines manipulation - delete empty lines.
Alternatively, for smaller files, one can search for that regex Ctrl+F, F3 and hit delete twice on each match.

hth,

Hello

Another possibility:
Search/replace dialog
Search for (normal search, not regular expressions): <Untitled>;
Check [x]Nonmatching
Press COPY button

It will copy all lines what doesn't contains "<Untitled>;" into new tab
