What's up everyone. Sorry for not updating sooner I've been really busy.
It seems that the computer just needed a reboot.
The night that happened I had a late session and it happened on the last project being worked on. I was just so tired I didn't even restart the computer, I just ended the session.
Looking back at it now, I remember on one of the projects getting that message from Logic that "A plugin has reported a problem and Logic needs to be rebooted". When I restarted Logic (but not the Mac Mini) everything seemed okay but I didn't have to use the group feature until the last project. I'm thinking now that had something to do with it and that I probably should've restarted the computer after that message.
Anyway, everything appears to be fine again as you can see from the picture.

@D.I. Johnson, the last time one of my devices updated by accident (my iPad that I use Logic remote on) it no longer allowed me to control Logic 10 so I had to upgrade everything and it cost me $2000.
I like some of the old Native Instruments plugins that I have and based on their website those plugins are now obsolete. They currently work with Logic 11.1.2 and I still have older projects that use them that I still need to work on. I don't want to do an update and find out those projects are missing sounds - really discouraging feeling.
The best advice I can give after this experience is for you to make sure whatever parameter your adjusting is doing what you're expecting it to do, that's how I noticed the groups weren't working properly.
Thanks for all the support. I always get good advice from this community.
