"Fast weapon Switch" Won't disable

Personally I don’t like the option for fast weapon switch,(where you scroll the mouse wheel and it changes weapons instead of giving you a menu). But when I untick the option and click ok it just checks itself again. Is there any way to turn it off? While I’m at it the sound option keeps setting itself to speakers even though I use headphones.

i love fast wep switch i always use it :3

did anyone find a fix? its stuck for me to and its really annoying.

Restart 1. Gmod
2. Computer
3. reinstall gmod
