I have used the staff roll to extend the length of the note and this works okay but I have just noticed that although the song is in 4/4 time, when I now go into Editable Notation Mode I still have four beats but each beat now has 3 vertical lines instead of the 4 that were there originally. Apart from changing the ending I haven't made any other changes.

Grateful for some help with this.
