Ok, yes. I think this was the issue. So when I removed the autostart from pm2 it now only boots up the one MagicMirror.
Now I’m just having problems to show the MMM-Globe module even though I have activated the OpenGL on the pi.

After I removed the autostart from mm.sh my “pm2 ls” command now shows:
