The easiest way to remove any of the midi-events, and thats what a text event is, is to use the # button on the notation window. It's just tot eh right of the B, D, P etc buttons and left of the lyric button.
Click 'edit lyrics' and you can change any text event of lyric. You can even add lyrics in the lead in bar
