I have done 

# systemctl restart procps

# sysctl -p

a few times and rebooted without success. I have even done systemctl daemon-reload in hopes of having systemd reread the files.

My Google Fu is failing on finding a solution that works. Does anyone have an idea why the restart of procps applies the changes but doesn't apply them on startup?

Yes, the procps service is enabled and is running before I do the restart.

Thanks
