What is it that you want to change about the notes?
Those dots (the ellipsis mark, right?) appear when the notes are too short on the screen to show the phonemes. To take a shot in the dark, Piapro sometimes doesn't let you resize notes if they're too small on the screen. You need to zoom in on them to make the mouse change to the double-arrow resize cursor that lets you change how long the note is. I don't know if that's the issue you're seeing in the Vocaloid 4 Editor, but if it is, that might be a solution.
