Dam man !!

So I've been annoying everyone, about the auto , semi auto thing, I've learned that's what it is , i also had a problem where I'd go to shoot someone and I'd accidentally melee someone instead of getting killed, so i think I've found the solution after changing the custom buttons around, the r2 now slides or goes into prone position i think and b now melees, I've only played one game, i got 6 kills on record but i think i killed someone before i died , these kills seemed fairly easy compared to others , have i actually found the best settings! Hopefully, annoyingly the game stopped by itself, what's going on with it ? Hopefully this can help someone else anyway
