Rapid fire problems

Rapid fire shoots but no arrows come out. I don’t know what causes this but it happens, usually when I am holding the fire button shooting a large group. Very annoying but not as annoying as trying to aim rapid fire and it shoots where my cursor isn’t. I can hold the cursor (mouse pointer) in one location, and watch rapid fire fire in 4 different locations. Why is that? Is there a auto targeting programmed in? I’m on a PC not a console, I use a mouse for precision targeting, I do not need auto target.

Please fix these two problems,
Thank you.
