To find source --> right click your game launcher and select open file location. Yes there should be more in that list. But thats EXACTLY how an unmodded game load order looks like. Means the only thing which is in effect currently is the stock ESM. Now when you add ESP files (downloaded from the web) and put it in your Data folder, there will be more choices in that list. Heres the thing when i do that it only opens up the game launcher. Theirs no config files. Unless im missing it, which is completely possible.
