I have just checked out the on-line manual and found no mention of sewing just one . Have you tried slowing down the machine enough to notice when the last stitch for each star is due, and just press the stop button, or take pressure off the pedal? Do you have a back stitch button? It should make a couple of securing stitches. That was all I did on my old machines to get the wanted number of stars or whatever - actually there was no stop/start button. Just takes a bit of practice.
