Layouter not working for mobile design

The layouter slides are working fine on desktop and tablet, sliding side to side. But when I tried to design for mobile, with a vertical slide, it got really weird. When the first slide is displayed and the others are not displayed, it looks and performs as expected. But when any other slide is displayed along with the 1st, I can scroll between slides even though the scroll bar is deactivated. The arrows work. And the slides don’t scale correctly. Also, there’s a blank space at the bottom of the other slides that I can’t get rid of, for correct layout. The 1st slide is the only one working properly.
