gathering still not fixed ?

i tryed to do my gethering today but it seems its still not fixed ?

i can put a multiplier but then it also multiplies the time 
when i add items it uses the items in the multiplier but it also still gives the basic ore 
even if i put it to 0 or -1

is there anything i can do to make this work or do i have to simply stop using the gather system from this plugin ?

If you only want to use a multiplier, make sure there are no items under "Additional Items"
