Halo 4 Campaign Carbine double shooting

Hey guys I just noticed while playing halo 4 campaign that the carbine seems a bit too sensitive or something. Sometimes I mean to fire once but it shoots twice. I don’t know if it’s my controller, my hands, or a bug of some sort. Is anyone else noticing the carbine sometimes shooting when you don’t mean for it to?

Just noticed it’s also happening with the bolt shot

Also just noticed the target sight lights on the light rifle jump up higher than the model does when I jump. Something is off in halo 4 right now
