I would like to clarify that there are some issues under Android device and when user tries to open the time slot context menu first. This cause all context menus to open and close at same moment so user is not able to select an menu item. I would like to clarify that our development team is working on fix for this problem.
Please excuse us for any inconveniences caused.
