In OBS you can use "Profiles" to have different recording/streaming configurations available to easily switch between. It's ok to only use one profile.
Weather Sources is actually the name of a Scene Collection--not just a a particular scene. You can add/remove/import/export both Profiles and Scene Collections from the program menu--you don't need to manually find the files in the filesystem. That part of the window always shows the running version, profile and collection.
