I suggest trying it with some other text or note app.
If you really want it in the Notes app and don't want to bother finding an installing a second app, you could probably paste it into a new email and then copy it again from there.
This is all untested guessing, so if it works for you please let me know.
BTW, what sight are you copying the list from? I may want to experiment with it myself later.
