Num 6 is not working for some reason, all other options are working for me thought.
Depending on the version of the trainer you're using Numpad 6 can be either "Stealth Mode" or "Undo Teleport" 🤔
In the latest version: 1.07 (PATCH 03.07.2018) from November 04, 2018 "Stealth Mode" is Numpad 0.
Can you verify?
