Auto walk on Huntsman mini thats not actived

Hi, I have a Huntsman mini and i dont have any macros or anything like that set up so its just setup as is out of the box. I find that when playing games my W, A and D keys can sometimes trigger auto walk when making fine movements even though its off via the game settings too. Its really annoying when trying to peak and all of a sudden….off you toddle….to your death as you just walk on out there lol. Anyone have any suggestions? Thanks in advance
