Scraping is what it's called when LaunchBox takes the name of a game you have, runs it through the LaunchBox Games Database and EmuMovies, gives you some results, and downloads the appropriate media for it within LaunchBox. Scrape As is a feature where when someone imports a platform, and uses a non-traditionally named system they can opt to scrape it as another. For example, I want a platform named NES, but NES doesn't exist in the Database so I will call it NES and Scrape It as Nintendo Entertainment System. This way media can be found, but I can still call the platform what ever I choose. You can also change a platform scrape as in the Tools -> Manage Platforms screen, however it doesn't look like that is your issue here.
I honestly can't say what it is at this point. A setting has to be off somewhere. Paths, names, cores, or some sort of setting. I don't know if you've followed our RetroArch tutorials, but there is a beginner one centered around SNES and assumes nothing, but I would suggest trying to watch that if you haven't already. If you have seen it, then I am even more confused to be honest.
