No red dot for unmonitored processes on pm2 ls

[jesobreira]

Quoting the docs:

How to disable monitoring for a specific process?
You can then use the command pm2 unmonitor [APP_NAME|ID] to stop monitoring a process with PM2 Plus. pm2 ls will display a red dot indicating the application will not be monitored by PM2 Plus. If you want to monitor the process again use pm2 monitor [APP_NAME|ID].

(emphasis added)

However, when I run pm2 ls on my servers, after removing some processes from PM2 Plus with "pm2 unmonitor", I cannot see any red dot in the list. Yet, I can confirm that the processes have been removed from PM2 Plus.

Which PM2 version are you using ?
