Shadow Box and the Masks Pen stroke tutorial - center - square- modifier not working

my version- zbrush 4r4
link to zbrush tutorial- http://www.youtube.com/watch?v=HIl83aMaCy0

my steps i selected the mask circle - and then stroke circle - and selected square and center - but know change occurred

the desired effect was for me to be able to select the middle and drag out a circle

but i noticed i couldn’t select directional in the stroke tab - modifier. if you could help me with that to it would be greatly appreciated

Thanks for reading
