You are describing the default behaviour.  Are you running an older
version and disabling conflict-detection or something?  DHCP's DDNS
has to use two updates, one to remove the A, another to remove the
DHCID IFF all A and AAAA records have been removed.  Is the second
update reliably failing for some reason?
