WorldGuard not working

So the config and the flags don't change anything. I've tried to make it so that you can use pumpkins as scuba helmets with the config and it didn't work (I'm using NotePad++ btw). I also set flags on regions and they don't work. This is really making me angry because I want to protect my spawn. I'm running WorldGuard version 5.2.2 and WorldEdit version 5.2
