weird bug with gmod keys and more proof with my .dll

So my keys are messing up when im injecting my example cheat or not (Develping a clientside/serverside anticheat that uses local hijacking etc, theory im working on, started making this for a test and found something strange)
anyways thought i would hook createmove to see how well its going and this happens.
I just reinstalled and its still happening.
Code:
10:12 PM - nup: bugs when i dont inject too
10:13 PM - nup: when i use mousewheel
10:13 PM - nup: but space works fine but thats bc its always got buttons & IN_JUMP
10:13 PM - nup: not just firing it once
10:13 PM - nup: but attack works fine
10:13 PM - nup: but thats bc its always got buttons & IN_ATTACK
10:13 PM - nup: not just firing it once per packet.
quick rundown i did to my friend.
video 1: local server

video 2: public server

no addons were enabled

literally reinstalled and bound mwheeldown +jump, still happening
