Does anyone know why the seat adjustment screen goes unresponsive or has some of the bars grayed out? I had massage on a while back and when I stopped it, it felt like one of the rollers was stuck in place. I tried to adjust it through the screen (and seat side) and felt like it didn't change much. several minutes later the screen said "refreshing seat settings" but again, didn't feel much change. I feel like this should be easy and intuitive, but there must be something I'm missing! TIA
