Do you have a CFW'd switch ?
If yes, then follow OP's tutorial, he gives links & information.
If not, then there's nothing you can do, unless your switch isn't "patched", check your switch's serial number and compare using google to know if it's patched or not.
"That is just how it has been. Game gets leaked earlier, PKHeX base support for that game is in official release.

Haven't had any problems with those codes so far, I've been able to encounter 8 without restarting.

Because they're in OP's file, which means they should work de facto, not that I care modifying them since it takes a second.
Edit : Oh alright you actually need to ... toggle a code to make another one work, while these ones doesn't require any other code, no offense, but that's terribly...
Only thing drive me crazy is all these new horror games nowadays is its so dark, all time. I can't even play them. I understand they trying to create spooky but be creative a little, not just darkness with pop out scare scenes.
