Message number indicator (red dot with a 1) will not go away even if all message are read

Using Glip v 19.05.2 (E. 2.0.14) Build 958. When I receive a message, the red indicator will appear on the taskbar icon. Once read it should go away. It usually did, but now, it will not go away no matter what I do. I have rebooted, checked my groups/users for any pending messages and nothing. It still keeps coming back. Now I can't tell if I have a valid new message or if it is the phantom message. Please help!
