This BUG occurs when my dwellers lose health (incidents, raid, Deathclaws) When i zoom out of the room, their health bars and names will not fade away. If i heal them or not does not matter. Sometimes zooming fully in and out fixes it but only once. It happens only after some time i play (5-10 minutes). Reloading the game fixes this, but after some time it happens again. It happens on all devices i play on. It does not matter how much rooms or dwellers i have. Providing screenshot (screenshot does not capture HUD and healthbars, only names, but ingame, healthbars of the three dwellers are also present.

I experience this same problem. Green bars over heads, sometimes it looks like bars and names behind them, too. Won't go away until I close app and reopen later.
