It seems that I merged two installation procedures and did, in fact, install PM2 startup twice. Resolution, for me, was to do a complete install, but to not do the PM2 autostart process until I was done doing everything else - I was not able to figure out how to remove one of the installations of PM2. Thanks for the help and info as I learn how to do this.

@sdetweil I will stop messing with it then. Thanks for the info.
