On Cisco ASA, You cannot have DHCPd and Relay configured at the same time.You can add different DHCP scope to the ASA DHCPd. It should be modifying the GIADDR (Relay Agent) field within the DHCP packet, thats where the relay IP is normally entered.So it looks that the IP address of the DHCP reply is substituted with the IP address of the ASA dmz interface as it is explained in the documentation.
