Default quantity is now the lowest one

I have just started testing this plugin, and it seems to do what it says, but I have one problem… I wanted it set a default quantity that in my case is going to be 100 (it is going to be cm, because of selling products by it’s lenght)…. I setled 100 as default quantity because (1 meter = 100cm is the usual start point) and it works, but then in the page I try to buy a lower quantity and it always set 100 as the minimum value… I think default quantity is not the same as minimum quantity is there any chance this problem could be solved?
