Scrolling issues

Hi!

I am trying to use some default icons from the available list and giving them “set selected/checked” and then trying to show/hide a mobile screen panel which has multiple scrolling options and a multiple “set panel state” functions. When i do this i just cannot scroll the screen in the preview. But, when i remove “set selected/checked” from the icon and then try to preview, it just starts scrolling back. Whats the relation between these two functions? Am i doing something wrong? Thanks in advance.
