I found that switching the fire mode to single fire displays the wrong icon, it swithches to what should be the icon representing full automatic fire (three bullets), same as for vice-verse. the exact same problem or glitch when a barrel attachment like shotgun/grenade 40mm is selected in multiplayer, the icon shows a shotgun when shooting with your bullets and auto-matic fire when I select the light shotgun, not the right icon is lit-up
