Welcome to Tom's!
On the Taskbar next to the individual Icons, is a small Triangle. left click it, and in the popup, left click on the word "Customize". Then in the window that opens, left click on the drop down menus for each Icon, and change the behaviors to "Only Show Notifications" This should put all the Icons in the little group. Also, make sure that the box for "Always show all icons" is not checked.
