Looks like SMF is working in the expected way.
I don't know what they did with the sets on Full House, but I think on That 70s Show they had the sets facing in different directions. At least this is what I recalls from watching the behind the scenes tour of That 70s Show that aired around the time that the show's finale. So the basment set faced one set of bleachers, the kitchen, driveway and garage faced a second set of bleachers, and the living room faced a third set of bleachers. Maybe something similar was done on Full House, with the main floor facing one set of bleachers, the upstairs facing a second set of bleachers, and the other sets facing other bleachers yet again.
