Help with menu on SMARTBOX theme for mobile

Hi I’m using the smartbox theme and have yet to make my site live via my main URL. However I have found that on a mobile platform, specifically android, when I hit the menu link the drop down portion of the menu expands, however I’m unable to select the SUB menu items and the drop down then vanishes. Is there perhaps something I’m doing wrong in a setting? or has anyone ever solved this before…?
