ADS keeps dropping and automatic pistol?

Had a weird glitch this Christmas. As I’m shooting someone, while aiming down sights, it goes right back to hip fire, while I’m still holding the aim button. At the same time, I switched to my pistol because I depleted my AR’s ammo, and lo ans behold… my pistol is automatic. It’s like someone put a glock switch on it. Even though one of these glitches is beneficial, I need to know how to fix it before I get accused of cheating or go negative KD. My control binds are perfectly fine. Idk what’s going on.
