Are you playing Pokemon Ultra Sun? If so, then those codes are different from it. I'm making the plugin for Ultra Moon because is the only one I've got right now. When I feel like there enough content in the ultra Moon plugin I'll install Ultra Sun an convert anything I can. I couldn't replicate any of those cheats in pokemon Ultra Moon. Try and download the latest version and try again (if you are playing Ultra Moon). I'm sorry. Once I have all cheats it will be easy to translate them into sun.
Yea I'm playing Ultra Sun so that would be the reason why I guess.
