It entirely has to do with the incorrect melee styles behind each of the options. This will hopefully be fixed very soon, but for the time being only use the following two styles (if you would like to hit anything other than zeros):

This will roughly give a +70% accuracy boost in most cases. This also clears up why some people thought the Scythe on the test server was different, while the code has not changed at all.
Thanks, and sorry for the inconvience!
