hermie...bummer. i'd keep the lst'd one; it will produce a greater yeild, pull of the male flowers as you see them to avoid a total seed plant. your beans will be useless, as they will all grow to be male or hermie.so your best bet is to discontinue or to work hard on one of them, keeping an eye out for those balls daily... i've done it, it can be done. just requires patience...

hope this helps sweetie
