Hatch problem

Hi there, I need some help to use the hatching function in Draftsight.

so sorry to bother you all but i can't find a useful guide in my native language (Italian) and the ones in English that i've found, they haven't the answer i'm looking for. (i'm testing this software since 2 days)

after that i've used hatch to fill my area (even a circle or rectangle just to keep it simple), obviusly keeping the "keep relation between hatch and boundaries" box checked, when i' try to edit the bounds, the hatch doesn't change, why?

it's quite frustrating and surely i messed with some little thick or option, but i need this function to work properly.

thanks for your help!
