Maybe you could check the title id and build id of your game is it matches to the cheat.
Different regions have different title ids
Nah mate, in this case they worked just fine... It's just that some of the newest updater homebrews somehow save a duplicate for the cheats in the root of the SD card. The first time I asked I had the folder in both atmosphere/contents/titleid/cheats and root/contents/titleid/cheats
To add insult to injury, the folder in the right location (atmosphere/contents) missed the .txt file. It was a set of empty folders! And that was because I made a copy/paste with the NX-Shell homebrew.
I plugged my SD in my computer, made a copy/paste of the .txt file, checked that it wasn't UTF-8 BOM, and plugged back into my Switch. Then it worked just fine. =)
