"Notepad++" is a windows program, while "sort" -- a UNIX utility -- is usually not installed on Windows. I can't tell how you're using the program, or on what system since you haven't said, but my first guess would be carriage returns are getting stripped out. Windows insists on those in text files, nearly anything else doesn't. How to remedy that depends on what you're doing where, and what utilities are available. You may even be able to just adjust settings in Notepad++ to not need carriage returns.
It's not a good idea to send it to the same file you're sorting for reasons you've already discovered: If something goes wrong, you've just destroyed all your input data. Which is very easy to do, because the most obvious way for people to try it (sort < inputfile > inputfile) is guaranteed to destroy your input data before sort even begins to read it.
