I think lastpass maybe has updated since you've published this because "Secure Notes" appear as "Notes". I'm not sure if it was always this way or not, but regardless, creating a folder called "Secure Notes" in the notes section, and a subfolder of "SSH" does not work. Nor does creating a folder of "SSH" at the root of the notes level. Please let me know if I'm not understanding correctly.
