Console commands not working

Game mode: [Singleplayer]
Problem: [ Bug ]
Region: [US]

I’m able to access the command console using the tilde ` key, but when I enter the EnableCheats command, none of the commands I have tried work (e.g. Fly, Invisibility, etc). Am I missing something? I’ve tried typing the command out or selecting from the list and neither method does anything.
