I'm running the same as you are and it works fine for me, here's my dhcp
config:

authoritative;
ddns-update-style ad-hoc;
ignore client-updates;

option domain-name "example.com";
option domain-name-servers 10.0.33.10, 10.0.33.9;
option time-servers ntp.example.com;
max-lease-time 7200;
default-lease-time 3600;
option netbios-node-type 8;

subnet 10.0.32.0 netmask 255.255.255.0 {
       option routers 10.0.32.1;
       option subnet-mask 255.255.255.0;
       range 10.0.32.200 10.0.32.230;
}

subnet 10.0.33.0 netmask 255.255.255.0 {
       option routers 10.0.32.1;
       option subnet-mask 255.255.255.0;
       range 10.0.33.200 10.0.33.230;
}
