Weapon animation replacers glitches

[Crowley9]

I'm using Weapon Animation Replacers mod, and I have run into minor glitches with the first-person pistol animations. I picked option 3, which has the player character holding the gun pointing upwards with both hands when not aiming. First glitch I have is that when I aim down the iron sights, the hands of my character do a weird motion of starting at the top of the screen, then very quickly circle down to the bottom of the screen. This also happens with option 1, which is pointing upwards with one hand, though there only the right hand does the half circle down. Another issue I have is that on some rare weapons aiming down the iron sights does not actually raise the gun itself to the aiming position. So far I have noticed this happening with Pew Pew and the Alien Blaster.
