@ltpaulieb you will only have a es_systems.cfg in /opt/retropie/emulationstation/configurations/all/ if you have copied it there yourself. It overrides the RetroPie managed one. If you want RetroPie to manage the systems, you should remove it (or manually keep it up to date).

@slydisciple glad you got it working.

@herb_fargus It's not a 3rd party image, it's someone's preconfigured noobs setup with 3 partitions: one with Retropie, one with Kodi, and one with Raspbian. It's still the default Retropie image on top of a headless raspbian os. It was done this way so you would have less overhead when running Retropie (rather than having Raspbian with the GUI with both Kodi and Retropie installed and running on it).
