Those menu items that you mentioned respond to HoverOver action when you move the mouse over them. You need to add additional step, that simulates the real user behavior before clicking on the element. We call it a HoverOver step, which will help expand the menu. You can add it from the Highlighter menu during recording, under Mouse Actions -> HoverOver.
Please give that a try and do not hesitate to contact us again, if you need further assistance.
