Having the 2 subnets in a shared-network block will cause dhcp to treat
them as the same, so it will hand out addresses from any one.

You should take them out of the "shared-network" block if they are separate
networks and then have ways for dhcpd to know from which subnet the request
was received. Either the dhcpd server must be connected with an interface
to each subnet or you need to set up a relay, or a combination.
