Hmm, I have a pretty good idea why this is the case, and could probably make a fix for when you just use the keyboard to see your own keys at least.
the problem why isnt showing on demo is because the code was made to get the movement/keypress of active/real users, not a "ghosts" like in demos. im already fixing that @Kameleon
This has been fixed by Cutie in a version of our UnityMod (Formerly known as KaMod) which has yet to be released. Figured I would update you on the matter
