Red line for "unread messages" not disappearing

Description

Hi, I am building a chatbot using Rasa and deploying it in RocketChat. I am using docker and followed the instructions from this page https://rocket.chat/docs/installation/docker-containers/docker-compose/.
I noticed that the red line which appears when there are unread messages does not disappear even after the message is read. Unless I reply to the message the red line stays there. Is there any way to fix this or disable the red line altogether?

Server Setup Information

  • Version of Rocket.Chat Server: 2.2.0
  • Deployment Method: docker
  • Number of Running Instances: 1
  • DB Replicaset Oplog: Enabled
  • NodeJS Version: 8.15.1 - x64
  • MongoDB Version: 4.0.13

Any additional Information

I tried using the 2.3.0 docker image but it has the same issue.
When I downgrade it to 2.1.1 the rocketchat instance doesn’t start and I get this message “Can’t find migration version 166”.
Any help would be highly appreciated. Thanks!
